xsk: Fix clang build error in __xp_alloc
Fix a build error with clang in __xp_alloc():
[...]
net/xdp/xsk_buff_pool.c:465:15: error: variable 'xskb' is uninitialized
when used here [-Werror,-Wuninitialized]
xp_release(xskb);
^~~~
This is correctly detected by clang, but not gcc. In fact, the xp_release()
statement should not be there at all in the refactored code, just remove it.
Fixes: 94033cd8e73b ("xsk: Optimize for aligned case")
