usb: gadget: g_ffs: remove a reduntant gfs_ether_setup variable
Since d6a0143985489e470a118605352f4b18df0ce142
usb: gadget: move the global the_dev variable to their users
"the_dev" variable can be used as a "setup done" flag; non-NULL
meaning "setup done", NULL meaning "setup not done". Moreover,
gether_cleanup() can be safely called with a NULL argument.
Corrected a comment to be consistent with the code.
