From: Jeremy Spewock <jspewock at iol.unh.edu>

There were two different commands in the hugepage mounting process that
were not using super-user privileges; one for unmounting hugepages and
another for re-mounting them. This patch adds the flag that enables
enhanced permissions for both of these actions.

Bugzilla ID: 1439
Fixes: b8bdc4c58f57 ("dts: replace pexpect with fabric")
