fault-injection: handle EI_ETYPE_TRUE
Commit af3b854492f351d1 ("mm/page_alloc.c: allow error injection") introduced EI_ETYPE_TRUE, but did not extend * lib/error-inject.c:error_type_string(), and * kernel/fail_function.c:adjust_error_retval() to accommodate for this change. Handle EI_ETYPE_TRUE in both functions appropriately by * returning "TRUE" in error_type_string(), * adjusting the return value to true (1) in adjust_error_retval(). Furthermore, simplify the logic of handling EI_ETYPE_NULL in adjust_error_retval().
