Pranjal Ramajor Asha Kanojiya 21ba0445e4 accel/qaic: Synchronize access to DBC request queue head & tail pointer ...

[ Upstream commit 52e59f7740 ]

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.
