[PATCH] fault-inject: define FAULT_ATTR_INITIALIZER when CONFIG_FAULT_INJECTION is disabled

[Mallesh Koujalagi]

Make FAULT_ATTR_INITIALIZER available without CONFIG_FAULT_INJECTION.
FAULT_ATTR_INITIALIZER is needed for struct initialization but is only
defined when CONFIG_FAULT_INJECTION=y. This breaks code that uses it in
compound literals where DECLARE_FAULT_ATTR cannot be used. Make the
macro available regardless of config to fix build issues.
