[PATCH 1/2] ipc/mq: Do not vaild queue attributes default/ceiling value If the user pass attr as NULL

[Sasikantha Babu]

Kernel should not validate queue attributes default/ceiling value while
creating a mqueue, if user pass attr as NULL. Otherwise In worst case
If the validation fails then sys_mq_open returns -EINVAL/-EOVERFLOW
which will make user clueless about reason for the failure.
