crypto: qat - reduce stack size with KASAN
Passing the register value by reference here leads a large amount of stack being
used when CONFIG_KASAN is enabled:
drivers/crypto/qat/qat_common/qat_hal.c: In function 'qat_hal_exec_micro_inst.constprop':
drivers/crypto/qat/qat_common/qat_hal.c:963:1: error: the frame size of 1792 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Changing the register-read function to return the value instead reduces the stack
size to around 800 bytes, most of which is for the 'savuwords' array. The function
now no longer returns an error code, but nothing ever evaluated that anyway.
