We mount efivarfs fail after pstore generated 'dump-type*' variables and
reboot.
This issue introduced by commit 47f531e8ba3bc3901a0c493f4252826c41dea1a1
(efivarfs: Validate filenames much more aggressively)
The pstore variable is 'dump-type*-*-*-*-GUID'style, it could not pass
the "GUID should be right after the first '-'" check. This patch allow
the variable name that has 'dump-type' pass the name check.
