[PATCH] Staging: wlan-ng: improve code aspect in p80211req_mibset_mibget()

[Claudiu Beznea]

This patch improves code aspect in p80211req_mibset_mibget() function
by removing accolades which followed case statements. To do so,
some data variable ware declared at the beginning of the
function and also pstr and key variables were initialized
only in the code which uses them.
