ipc/mqueue.c: fix mq_open() return value
We return ENOMEM from mqueue_get_inode even when we have enough memory.
Namely in case the system rlimit of mqueue was reached. This error
propagates to mq_queue and user sees the error unexpectedly. So fix
this up to properly return EMFILE as described in the manpage:
EMFILE The process already has the maximum number of files and
message queues open.
instead of:
ENOMEM Insufficient memory.
With the previous patch we just switch to ERR_PTR/PTR_ERR/IS_ERR error
handling here.
