ice: refactor mailbox overflow detection

Jake Keller says:

The primary motivation of this series is to cleanup and refactor the mailbox
overflow detection logic such that it will work with Scalable IOV. In
addition a few other minor cleanups are done while I was working on the
code in the area.

First, the mailbox overflow functions in ice_vf_mbx.c are refactored to
store the data per-VF as an embedded structure in struct ice_vf, rather than
stored separately as a fixed-size array which only works with Single Root
IOV. This reduces the overall memory footprint when only a handful of VFs
are used.

The overflow detection functions are also cleaned up to reduce the need for
multiple separate calls to determine when to report a VF as potentially
malicious.

Finally, the ice_is_malicious_vf function is cleaned up and moved into
ice_virtchnl.c since it is not Single Root IOV specific, and thus does not
belong in ice_sriov.c

I could probably have done this in fewer patches, but I split pieces out to
hopefully aid in reviewing the overall sequence of changes. This does cause
some additional thrash as it results in intermediate versions of the
refactor, but I think its worth it for making each step easier to
understand.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: call ice_is_malicious_vf() from ice_vc_process_vf_msg()
  ice: move ice_is_malicious_vf() to ice_virtchnl.c
  ice: print message if ice_mbx_vf_state_handler returns an error
  ice: pass mbxdata to ice_is_malicious_vf()
  ice: remove unnecessary &array[0] and just use array
  ice: always report VF overflowing mailbox even without PF VSI
  ice: declare ice_vc_process_vf_msg in ice_virtchnl.h
  ice: initialize mailbox snapshot earlier in PF init
  ice: merge ice_mbx_report_malvf with ice_mbx_vf_state_handler
  ice: remove ice_mbx_deinit_snapshot
  ice: move VF overflow message count into struct ice_mbx_vf_info
  ice: track malicious VFs in new ice_mbx_vf_info structure
  ice: convert ice_mbx_clear_malvf to void and use WARN
  ice: re-order ice_mbx_reset_snapshot function
