md: wait for pending superblock updates before switching to read-only
If a superblock update is pending, wait for it to complete before
letting md_set_readonly() switch to readonly.
Otherwise we might lose important information about a device having
failed.
For external arrays, waiting for superblock updates can wait on
user-space, so in that case, just return an error.
