Yewon ChoiandGreg Kroah-Hartman 2c0cbb97b1 xsk: Skip polling event check for unbound socket ...

[ Upstream commit e4d008d49a ]

In xsk_poll(), checking available events and setting mask bits should
be executed only when a socket has been bound. Setting mask bits for
unbound socket is meaningless.

Currently, it checks events even when xsk_check_common() failed.
To prevent this, we move goto location (skip_tx) after that checking.

Fixes: 1596dae2f1 ("xsk: check IFF_UP earlier in Tx path")
