I am seeing that error message on a Surface Pro 2017. The connection appears stable regardless of powersaving but after suspending I get:
[ 361.092570] mwifiex_pcie 0000:01:00.0: Firmware wakeup failed
Followed by an endless loop of:
[ 366.098914] mwifiex_pcie 0000:01:00.0: PREP_CMD: FW in reset state
[ 366.098926] mwifiex_pcie 0000:01:00.0: scan failed: -1
