Re: p80211wext.c: problem with IW_ENCODE_ALG_WEP

From: Julia Lawall <julia@xxxxxxx>

The expression !(ext->alg & IW_ENCODE_ALG_WEP) appears to be incorrect,
because there are several possible values for ext->alg that give 1 when
bit-anded with IW_ENCODE_ALG_WEP. Therefore Richard Kennedy suggested to
rewrite the code with !=

Added \n at the end of the debug string as well.
