xsk: Fix xsk_poll()'s return type
[ Upstream commit 5d946c5abbaf68083fa6a41824dd79e1f06286d8 ]
xsk_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.
