ARM: 7812/1: rwlocks: retry trylock operation if strex fails on free lock
commit 00efaa0250939dc148e2d3104fb3c18395d24a2d upstream.
Commit 15e7e5c1ebf5 ("ARM: 7749/1: spinlock: retry trylock operation if
strex fails on free lock") modifying our arch_spin_trylock to retry the
acquisition if the lock appeared uncontended, but the strex failed.
This patch does the same for rwlocks, which were missed by the original
patch.
