scsi: libfc: Fix use after free in fc_exch_abts_resp()
[ Upstream commit 271add11994ba1a334859069367e04d2be2ebdd4 ]
fc_exch_release(ep) will decrease the ep's reference count. When the
reference count reaches zero, it is freed. But ep is still used in the
following code, which will lead to a use after free.
Return after the fc_exch_release() call to avoid use after free.
