Subject: [PATCH v2] Staging: rtl8192u: Fix coding style issues at ieee80211_crypt_wep.c

Merge two pr_debug lines with literal strings splitted across several lines
into one single line, simplifying prism2_wep_init error check code.
Openning braces should never be in a new line, move them to the end of
the previous line.
Removed two useless lines at ieee80211_wep_null.
