HID: playstation: Add missing check for input_ff_create_memless

The ps_gamepad_create() function calls input_ff_create_memless()
without verifying its return value,  which can lead to incorrect
behavior or potential crashes when FF effects are triggered.

Add a check for the return value of input_ff_create_memless().
