Subject: [PATCH] scsi: fnic: Zero io_cmpl_skip on fw reset completion
Git-commit: 1cdf8bc18f1ee43a39e543506fff8d5db3020ae1
Patch-mainline: v4.13-rc1
References: FATE#322783
io_cmpl_skip keep track of number of completions to skip when stats are
reset. If a fw_reset happens immediately after stats reset it could put
it out of sync so need to reset io_cmpl_skip when fw reset is completed.
