wlan:Dont parse the IE if it's length is not in the range

Added a conditional check to verify whether the IE length
is greater than the expected length.If it is not then the IE
will not be parsed.

Problem:DUT got crashed when it tried to parse an IE with wrong
length '0'.This is reported on Buggy customer AP.
