nvme: remove unused timeout parameter

The function __nvme_submit_sync_cmd() has following list of callers
that sets the timeout value to 0 :-

        Callers               |   Timeout value
------------------------------------------------
nvme_submit_sync_cmd()        |        0
nvme_features()               |        0
nvme_sec_submit()             |        0
nvmf_reg_read32()             |        0
nvmf_reg_read64()             |        0
nvmf_reg_write32()            |        0
nvmf_connect_admin_queue()    |        0
nvmf_connect_io_queue()       |        0

Remove the timeout function parameter from __nvme_submit_sync_cmd() and
adjust the rest of code accordingly.
