Subject: SCSI: Fix incorrect memset in bnx2fc_parse_fcp_rsp

From: Andi Kleen <andi@xxxxxxxxxxxxxx>

commit 16da05b1158d1bcb31656e636a8736a663b1cf1f upstream.

gcc 4.8 warns because the memset only clears sizeof(char *) bytes, not
the whole buffer. Use the correct buffer size and clear the whole sense
buffer.

/backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c: In
function 'bnx2fc_parse_fcp_rsp':
/backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c:1810:41:

the destination; did you mean to provide an explicit length?
