wifi: carl9170: cmd: downgrade transient register I/O errors to wiphy_dbg

Browse source

Register read/write failures during deauth/teardown transitions are
harmless — mac80211 tries to read survey stats or write slot_time
while the firmware is in a transitional state.  The command times
out with -EIO but the adapter recovers and re-authenticates normally.

Downgrade both "writing reg ... failed" and "reading regs failed"
from wiphy_err to wiphy_dbg to reduce dmesg noise.  The errors are
still visible with dynamic debug enabled for investigation.
