[PATCH -block] fault-inject: fix build error when FAULT_INJECTION_CONFIGFS=y and CONFIGFS_FS=m

[Akinobu Mita]

This fixes a build error when CONFIG_FAULT_INJECTION_CONFIGFS=y and
CONFIG_CONFIGFS_FS=m.

Since the fault-injection library cannot built as a module, avoid building
configfs as a module.
