staging: r8188eu: use list_head for xmitframe list
The r8188eu driver defines a struct __queue that contains a list_head and
a spinlock.
struct tx_servq describes a station for which we have pending tx packets.
This struct contains a __queue for the pending packets (a __queue of
struct xmit_frame entries). In this particular case, the queue's spinlock
is not used, we need only the list_head.
rtw_dequeue_xframe uses a local variable for such an xmit_frame queue.
This patch replaces this variable with a list_head.
