pwm: jz4740: Don't use dev_err_probe() in .request() 

commit 9320fc509b upstream.

dev_err_probe() is only supposed to be used in probe functions. While it
probably doesn't hurt, both the EPROBE_DEFER handling and calling
device_set_deferred_probe_reason() are conceptually wrong in the request
callback. So replace the call by dev_err() and a separate return
statement.

This effectively reverts commit c0bfe9606e ("pwm: jz4740: Simplify
with dev_err_probe()").
