[PATCH][-next] mqueue: fix incorrect memset size for object v

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The size of the memset is incorrect, it is currently using the size
of attr (a struct mq_attr *) and not of v (a struct compat_mq_attr)

Detected by CoverityScan, CID#1449362 ("Wrong sizeof argument")

Fixes: 045256d59da6 ("mqueue: move compat syscalls to native ones")
