crypto: qat - disregard spurious PFVF interrupts
[ Upstream commit 18fcba469ba5359c1de7e3fb16f7b9e8cd1b8e02 ]
Upon receiving a PFVF message, check if the interrupt bit is set in the
message. If it is not, that means that the interrupt was probably
triggered by a collision. In this case, disregard the message and
re-enable the interrupts.
