Subject: [PATCH 4.9 42/47] Revert "cifs: Set CIFS_MOUNT_USE_PREFIX_PATH flag on setting cifs_sb->prepath."

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

This reverts commit 742300e32db00f008e944acafaeba9a12730eff0 which is
commit a738c93fb1c17e386a09304b517b1c6b2a6a5a8b upstream.

It is reported to cause problems in older kernels, so revert it for now
until we can figure it out...
