[PATCH AUTOSEL 4.14 155/371] soc/fsl/qe: Fix an error code in qe_pin_request()

[Sasha Levin]

From: Dan Carpenter <dan.carpen...@oracle.com>

[ Upstream commit 5674a92ca4b7e5a6a19231edd10298d30324cd27 ]

We forgot to set "err" on this error path.

Fixes: 1a2d397a6eb5 ("gpio/powerpc: Eliminate duplication of 
of_get_named_gpio_flags()")
