Radosław Piliszek 21488710d6 Fix Swift with kernel 4.19 and later

We mount Swift volumes with xfs.
The 'nobarrier' option we used was made noop [1]
and deprecated [2] (with warning) in kernel 4.10.
In 4.19 it was removed [3] resulting in an error
when using e.g. Debian Buster as host.
The noop patch was backported to CentOS 7 so
it is safe to remove this option with no behavior
change and backport to where needed.
Ubuntu Bionic uses 4.15 which only warns.
CentOS 8 uses 4.18 which only warns as well.
Debian Buster uses 4.19 exactly which breaks.
