24b960c5c0 rtl8188eu: Change some locking around rtw_get_sec_ie() 
Routine rtw_get_sec_ie() appears to suffer from a bug triggered under
unusual circumstances. This bug is exposed by first sending a deauthentication
frame and at the same time sending a much larger frame. After doing some debugging
the cause of the lockup of the CPU was that while rtw_get_sec_ie() attempts to
read the beacon frame sent by the router/AP, the size of the beacon is changed
since it is a reference and not a copy. By having a "rogue" beacon frame being
very large which isn't normal and not considered in the design, the computer
was stuck in an endless CPU lockup.

Routine translate_scan(), which calls rtw_get_sec_ie() is protected by a
spinlock. Add that spinlock around other calls of the routine.
