[PATCH 5.15.y] scsi: lpfc: Fix memory leak in lpfc_sli4_driver_resource_setup()

[Sasha Levin <sashal@kernel.org>]

From: Abdun Nihaal <nihaal@cse.iitm.ac.in>

[ Upstream commit 1bd28625e25be549ee7c47532e7c3ef91c682410 ]

The memory allocated for mboxq using mempool_alloc() is not freed in
some of the early exit error paths. Fix that by moving the
mempool_free() call to an earlier point after last use.

Fixes: d79c9e9d4b3d ("scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware.")
