Subject: [PATCH 19/20] staging: r8188eu: rtw_init_hwxmits is not needed

The _rtw_init_xmit_priv function calls rtw_alloc_hwxmits to allocate
memory for pxmitpriv->hwxmits (this is an array of struct hw_xmit). This
allocation uses kzalloc, the allocated memory is initialised with 0.

After the allocation, _rtw_init_xmit_priv calls rtw_init_hwxmits to set an
element of each hw_xmit to 0. This is not necessary, we can remove the
rtw_init_hwxmits call and the now unused function rtw_init_hwxmits.
