md: use msleep() in md_notify_reboot()

mainline inclusion
from mainline-v5.18-rc1
commit 7d959f6e
category: bugfix
bugzilla: 188015, https://gitee.com/openeuler/kernel/issues/I6OERX
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=7d959f6e978cbbca90e26a192cc39480e977182f

--------------------------------

Calling mdelay(1000) from process context, even while a reboot
is in progress, does not make sense.

Using msleep() allows other threads to make progress.
