[PATCH v2 3/4] mm/vmalloc: be more explicit about supported gfp flags.

[Michal Hocko <mhocko@kernel.org>]

From: Michal Hocko <mhocko@suse.com>

b7d90e7a5ea8 ("mm/vmalloc: be more explicit about supported gfp flags")
has been merged prematurely without the rest of the series and without
addressed review feedback from Neil. Fix that up now. Only wording is
changed slightly.
