HID: pidff: fix error return code in hid_pidff_init()
[ Upstream commit 3dd653c077efda8152f4dd395359617d577a54cd ]
Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.
Fixes: 224ee88fe395 ("Input: add force feedback driver for PID devices")
