crypto: qat - check return code of qat_hal_rd_rel_reg()
[ Upstream commit 96b57229209490c8bca4335b01a426a96173dc56 ]
Check the return code of the function qat_hal_rd_rel_reg() and return it
to the caller.
This is to fix the following warning when compiling the driver with
clang scan-build:
drivers/crypto/qat/qat_common/qat_hal.c:1436:2: warning: 6th function call argument is an uninitialized value
