Subject: [PATCH] usb: gadget: ffs: call functionfs_unbind() if
 _ffs_func_bind() fails

Function ffs_do_functionfs_bind() calls functionfs_bind() which allocates
usb request and increments refcounts. These things needs to be cleaned
up by if further steps of initialization fail by calling functionfs_unbind().
