[UNIX]: The unix_nr_socks limit can be exceeded
The unix_nr_socks value is limited with the 2 * get_max_files() value,
as seen from the unix_create1(). However, the check and the actual
increment are separated with the GFP_KERNEL allocation, so this limit
can be exceeded under a memory pressure - task may go to sleep freeing
the pages and some other task will be allowed to allocate a new sock
and so on and so forth.
So make the increment before the check (similar thing is done in the
sock_kmalloc) and go to kmalloc after this.
