usb: gadget: fix potential double-free in m66592_probe.
[ Upstream commit 44734a594196bf1d474212f38fe3a0d37a73278b ]
m66592_free_request() is called under label "err_add_udc"
and "clean_up", and m66592->ep0_req is not set to NULL after
first free, leading to a double-free. Fix this issue by
setting m66592->ep0_req to NULL after the first free.
