[PATCH v8 14/25] arm64: trans_pgd: pass NULL instead of init_mm to *_populate functions

[Pavel Tatashin]

trans_pgd_* should be independent from mm context because the tables that
are created by this code are used when there are no mm context around, as
it is between kernels. Simply replace mm_init's with NULL.
