[PATCH] loop.c warning removal
From: Rusty Russell <rusty@rustcorp.com.au>
loop.c has one of those places where manipulating own refcounts is safe: to
get into the ioctl handler you need to have the device open, so that holds a
refcount already (verified that this actually happens).
The compile warning is irritating.
