adb: only call autopoll callbacks when autopoll is not blocked 

Handle this at the ADB bus level so that individual implementations do not need
to handle this themselves.

Finally add an assert() into adb_request() to prevent developers from accidentally
making an explicit ADB request without blocking autopoll.
