misc: microchip: pci1xxxx: Fix a memory leak in the error handling of gp_aux_bus_probe()
[ Upstream commit 77427e3d5c353e3dd98c7c0af322f8d9e3131ace ] 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.")
