Add support for injecting ENOSPC or EIO errors. This needs to be enabled
by CONFIG_CACHEFILES_ERROR_INJECTION=y. Once enabled, ENOSPC on things
like write and mkdir can be triggered by:
echo 1 >/proc/sys/cachefiles/error_injection
and EIO can be triggered on most operations by:
echo 2 >/proc/sys/cachefiles/error_injection
