[PATCH 2/2] misc: microchip: pci1xxxx: Fix a memory leak in the error handling of gp_aux_bus_probe()

[Yongzhi Liu]

There is a memory leak (forget to free allocated buffers) in a
memory allocation failure path.

Fix it to jump to the correct error handling code.

Fixes: 393fc2f5948f ("misc: microchip: pci1xxxx: load auxiliary bus driver for the PIO function in the multi-function endpoint of pci1xxxx device.")
