Subject: scsi: lpfc: Remove extra atomic_inc on cmd_pending in queuecommand
after VMID
Patch-mainline: v5.20-rc1
Git-commit: 0948a9c5386095baae4012190a6b65aba684a907
References: bsc#1201956
VMID introduced an extra increment of cmd_pending, causing double-counting
of the I/O. The normal increment ios performed in lpfc_get_scsi_buf.
