uio: fix wrong return value from uio_mmap()
uio_mmap has multiple fail paths to set return value to nonzero then
goto out. However, it always returns *0* from the *out* at end, and
this will mislead callers who check the return value of this function.
Fixes: 57c5f4df0a5a0ee ("uio: fix crash after the device is unregistered")
