André Goddard Rosa a3ed2a1571 mqueue: fix kernel BUG caused by double free() on mq_open()
In case of aborting because we reach the maximum amount of memory which
can be allocated to message queues per user (RLIMIT_MSGQUEUE), we would
try to free the message area twice when bailing out: first by the error
handling code itself, and then later when cleaning up the inode through
delete_inode().
