[ Upstream commit 5b7419ae1d208cab1e2826d473d8dab045aa75c7 ]
In _rtw_init_xmit_priv, we use the res variable to store the error
return from the newly converted rtw_alloc_hwxmits function. Sadly, the
calling function interprets res using _SUCCESS and _FAIL still, meaning
we change the semantics of the variable, even in the success case.
This leads to the following on boot:
r8188eu 1-2:1.0: _rtw_init_xmit_priv failed
In the long term, we should reverse these semantics, but for now, this
fixes the driver. Also, inside rtw_alloc_hwxmits remove the if blocks,
as HWXMIT_ENTRY is always 4.
Fixes: f94b47c6bde6 ("staging: r8188eu: add check for kzalloc")
