staging: rtl8188eu: core: fix null dereference on exit path in rtw_mlme.c
If adapter is null, null dereference may occur. This patch fixes it.
The following Coccinelle semantic patch was used to find the case.
@@
expression E, E1;
identifier f;
statement S1,S2,S3;

* if (E == NULL)

... when != if (E == NULL) S1 else S2
when != E = E1
* E->f
... when any
return ...;
}
else S3
