platform/x86: hp_accel: Fix an error handling path in 'lis3lv02d_probe()'

If 'led_classdev_register()' fails, some additional resources should be
released.

Add the missing 'i8042_remove_filter()' and 'lis3lv02d_remove_fs()' calls
that are already in the remove function but are missing here.

Fixes: 9e0c79782143 ("lis3lv02d: merge with leds hp disk")
