[openib-general] [PATCH] opensm: rwlock double-release fix.

[Sasha Khapyorsky]

When the port is removed from subnet, but previously requested pkey
table block is received after this - the lock will be released twice.
This leads to deadlocks later when other MAD processor will try to
acquire the same lock.
