cachefiles: fix error return code in cachefiles_ondemand_copen()
The cache_size field of copen is specified by the user daemon.
If cache_size < 0, then the OPEN request is expected to fail,
while copen itself shall succeed. However, returning 0 is indeed
unexpected when cache_size is an invalid error code.
Fix this by returning error when cache_size is an invalid error code.
Changes

Fixes: c8383054506c ("cachefiles: notify the user daemon when looking up cookie")
