xwayland: Fix copy and paste error

This leg of the if/else ladder is a duplicate of the previous conditional.

It appears to have been intended to log enter events, but we already
handle those earlier. The drop event is already logged as well,
so let's just discard this branch entirely.

Fixes #552
