usb: gadget: net2272: Fix a memory leak in an error handling path in 'net2272_plat_pr...

BugLink: https://bugs.launchpad.net/bugs/1879759
commit ccaef7e6e354fb65758eaddd3eae8065a8b3e295 upstream.

'dev' is allocated in 'net2272_probe_init()'. It must be freed in the error
handling path, as already done in the remove function (i.e.
'net2272_plat_remove()')

Fixes: 90fccb529d24 ("usb: gadget: Gadget directory cleanup - group UDC drivers")
