firmware: xilinx: Fix an error handling path in 'zynqmp_firmware_probe()'

Browse source 
If 'mfd_add_devices()' fails, we must undo 'zynqmp_pm_api_debugfs_init()'
otherwise some debugfs directory and files will be left.

Just move the call to 'zynqmp_pm_api_debugfs_init()' a few lines below to
fix the issue.
