zwp_virtual-keyboard: fix mmap error handling

Browse source 
If mmap fails, it will return MAP_FAILED not NULL. Since the error
handling was incorrectly checking for NULL, MAP_FAILED was being passed
to xkb_keymap_new_from_string, on mmap failure, causing a segfault.
This just fixes the error checking.
