[PATCH 2/4] gpio: zynqmp: Remove unused variable ret

[Ashok Reddy Soma]

From: Algapally Santosh Sagar <santoshsagar.algapa...@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].

Remove variable ret.
