Subject: [PATCH v3 2/2] arm64/mm: Rename try_pgd_pgtable_alloc_init_mm

With BUG_ON in pgd_pgtable_alloc_init_mm moved up to higher layer,
gfp flags is the only difference between try_pgd_pgtable_alloc_init_mm
and pgd_pgtable_alloc_init_mm. Hence rename the "try" version
to pgd_pgtable_alloc_init_mm_gfp.
