Smatch reports that:
drivers/net/wireless/mediatek/mt7601u/debugfs.c:130
mt7601u_init_debugfs() warn: 'dir' is an error pointer or valid".
Debugfs code is not supposed to need error checking so instead of
changing this to if (IS_ERR()) the correct thing is to just delete
the dead code.
Fixes: c869f77d6abb ("add mt7601u driver")
