staging: rtl8192u: compare strcmp result to zero
Add " == 0" to the condition in both else if branches to address a
possible bug. strcmp returns 0 when its arguments are equal, which
evaluates to false, often leading to errors when used in if statements.
Currently, the statement in the first else if branch does not execute
when its arguments are equal, but it does execute when crypt->ops->name
equals any string other than "WEP" or "TKIP".
Similarly, the second else if branch does not execute when its arguments
are equal, and it only executes when crypt->ops->name equals "TKIP".
The else branch never executes.
It is unlikely that this is working as intended.
