 CIFS_MOUNT_USE_PREFIX_PATH flag on setting cifs_sb->prepath.

Hi Salvatore and Santiago,

Thanks for testing this out.

@Greg Kroah-Hartman: The reverted patch used in combination with Paulo's fix seems to fix both use cases. 
Can we have both these taken in on stable kernels? Paulo's patch is needed only for kernels 5.10 and older.

Regards,
Shyam

I re-applied commit a738c93fb1c1 ("cifs: Set CIFS_MOUNT_USE_PREFIX_PATH flag on setting cifs_sb->prepath.") and on top of that your provided patch, and this seems to resolve the issue for the testcase I have at hand!
