gpio: zynq: Check return value of pm_runtime_get_sync
[ Upstream commit a51b2fb94b04ab71e53a71b9fad03fa826941254 ]
Return value of "pm_runtime_get_sync" API was neither captured nor checked.
Fixed it by capturing the return value and then checking for any warning.
Addresses-Coverity: "check_return"
