pgsql: Remove volatile qualifiers from shm_mq.c. - Mailing list pgsql-committers

Remove volatile qualifiers from shm_mq.c.

Since commit 0709b7ee, spinlock primitives include a compiler barrier
so it is no longer necessary to access either spinlocks or the memory
they protect through pointer-to-volatile.  Like earlier commits
e93b6298, d53e3d5f, 430008b5, 8f6bb851, df4077cd.
