accel/qaic: Synchronize access to DBC request queue head & tail pointer
[ Upstream commit 52e59f7740ba23bbb664914967df9a00208ca10c ]
Two threads of the same process can potential read and write parallelly to
head and tail pointers of the same DBC request queue. This could lead to a
race condition and corrupt the DBC request queue.
