video: fbdev: vesafb: add missing mtrr_del() for added MTRR

The MTRR added was never being deleted, in order to store the
MTRR cookie we need to make use of the private info->par so we
create a struct for this. This driver was already using the extra
space typically used for info->par for the info->pseudo_palette
which typically used stuffed on driver's own private structs
(the respective info->par), so we just move the pseudo_palette
into the private struct as well.
