[PATCH v2 2/4] gpio: zynqmp: Handle error from get_gpio_modepin

[Ashok Reddy Soma]

From: Algapally Santosh Sagar <santoshsagar.algapally at amd.com>

There is a unused variable ret, due to which we are getting sparse warning
as below.
warning: variable 'ret' set but not used [-Wunused-but-set-variable].

Return ret incase of error.

Changes in v2:
 - Instead of removing ret variable, take it and return incase of error.
 - Updated description as per this.
