Yongzhi Liu 86c9713602 misc: microchip: pci1xxxx: fix double free in the error handling of gp_aux_bus_probe()
commit 086c6cbcc563c81d55257f9b27e14faf1d0963d3 upstream.

When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function
gp_auxiliary_device_release() calls ida_free() and
kfree(aux_device_wrapper) to free memory. We should't
call them again in the error handling path.

Fix this by skipping the redundant cleanup functions.

Fixes: 393fc2f594 ("misc: microchip: pci1xxxx: load auxiliary bus driver for the PIO function in the multi-function endpoint of pci1xxxx device.")
