staging: greybus: uart: return tty_alloc_driver() errors

Browse source

gb_tty_init() maps any tty_alloc_driver() failure to -ENOMEM.
tty_alloc_driver() currently always returns -ENOMEM on failure,
so this does not change behavior in practice. However, returning
PTR_ERR(gb_tty_driver) is more correct and consistent with kernel
conventions, preserving any future error codes the function might
return.
