Subject: [PATCH AUTOSEL 5.15 03/10] ksmbd: don't update ->op_state as OPLOCK_STATE_NONE on error

From: Namjae Jeon <linkinjeon@...nel.org>

[ Upstream commit cd80ce7e68f1624ac29cd0a6b057789d1236641e ]

ksmbd set ->op_state as OPLOCK_STATE_NONE on lease break ack error.
op_state of lease should not be updated because client can send lease
break ack again. This patch fix smb2.lease.breaking2 test failure.
