mt7601u: fix bbp version check in mt7601u_wait_bbp_ready
Fix bbp ready check in mt7601u_wait_bbp_ready. The issue is reported by
coverity with the following error:
Logical vs. bitwise operator
The expression's value does not depend on the operands; inadvertent use
of the wrong operator is a likely logic error.
Addresses-Coverity-ID: 1309441 ("Logical vs. bitwise operator")
Fixes: c869f77d6abb ("add mt7601u driver")
