[PATCH] block: show operation in error injection rules

[Jackie Liu <liu.yun@linux.dev>]

From: Jackie Liu <liuyun01@kylinos.cn>

Rules listed through the error_injection debugfs file omit the block
operation they match.  As a result, rules that differ only in operation
are indistinguishable even though op is mandatory when adding a rule.
