cursor: Add a more general check for infinite/NaN cursor position

Browse source 
It should be considered a bug if a compositor sets a non-finite
cursor position, so fail loudly (in debug builds) if that happens.

The existing check in wlr_cursor_warp_closest() is now redundant,
and would silently hide such bugs, so remove it.
