Subject: [PATCH 2/7] devices file: fail if --devicesfile filename doesn't
exist
A typo of the filename after --devicesfile should result in a
command error rather than the command falling back to using no
devices file at all. Exception is vgcreate|pvcreate which
create a new devices file if the file name doesn't exist.
(cherry picked from commit bfe072e4388b530cbf5369be8a8f1305220198bf)
