Subject: staging: fbtft: Don't spam logs when probe is deferred

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 37667f6e57712cef5652fa67f1cbd1299e204d94 ]

When requesting GPIO line the probe can be deferred.
In such case don't spam logs with an error message.
This can be achieved by switching to dev_err_probe().

Fixes: c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor interface")
