spi: pxa2xx: Balance runtime PM enable/disable on error
[ Upstream commit 1274204542f683e1d8491ebe9cc86284d5a8ebcc ]
Don't undo the PM initialization if we error out before we managed to
initialize it. The call to pm_runtime_disable() without being preceded
by pm_runtime_enable() would disturb the balance of the Force.
In practice, this happens if we fail to allocate any of the GPIOS ("cs",
"ready") due to -EPROBE_DEFER because we're getting probled before the
GPIO driver.
