mainline inclusion
from mainline-4.20-rc1
commit f8f83d8ffeb47041ff0937ecac6d10bcb388cd9f
category: bugfix
bugzilla: 16584
CVE: NA
---------------------------

After 9e1cc0a5 ("md: use mddev_suspend/resume instead of ->quiesce()")
We still have similar left in bitmap functions.

Replace quiesce() with mddev_suspend/resume.

Also move md_bitmap_create out of mddev_suspend. and move mddev_resume
after md_bitmap_destroy. as we did in set_bitmap_file.
