USB: gadget: bcm63xx_udc: fix memory leak with using debugfs_lookup()
[ Upstream commit a91c99b1fe5c6f7e52fb932ad9e57ec7cfe913ec ]
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once.
