Yewon Choi 52287ed416 rds: introduce acquire/release ordering in acquire/release_in_xmit() 
[ Upstream commit 1422f28826 ]

acquire/release_in_xmit() work as bit lock in rds_send_xmit(), so they
are expected to ensure acquire/release memory ordering semantics.
However, test_and_set_bit/clear_bit() don't imply such semantics, on
top of this, following smp_mb__after_atomic() does not guarantee release
ordering (memory barrier actually should be placed before clear_bit()).

Instead, we use clear_bit_unlock/test_and_set_bit_lock() here.

Fixes: 0f4b1c7e89 ("rds: fix rds_send_xmit() serialization")
Fixes: 1f9ecd7eac ("RDS: Pass rds_conn_path to rds_send_xmit()")
