tpm: tpm_try_transmit() refactor error flow.

commit 01f54664a4db0d612de0ece8e0022f21f9374e9b upstream.

First, rename out_no_locality to out_locality for bailing out on
both tpm_cmd_ready() and tpm_request_locality() failure.
Second, ignore the return value of go_to_idle() as  it may override
the return value of the actual tpm operation, the go_to_idle() error
will be caught on any consequent command.
Last, fix the wrong 'goto out', that jumped back instead of forward.
