scsi: lpfc: don't dereference dma_buf->iocbq before null check
From: Colin Ian King <colin.king@canonical.com>
dma_buf->iocbq is being dereferenced immediately before it is
being null checked, so we have a potential null pointer dereference
bug. Fix this by only dereferencing it only once we have passed
a null check on the pointer.
