[PATCH v13 29/70] mm/mmap: change do_brk_munmap() to use do_mas_align_munmap()

From: "Liam R. Howlett" <Liam.Howlett@Oracle.com>

do_brk_munmap() has already aligned the address and has a maple tree state
to be used. Use the new do_mas_align_munmap() to avoid unnecessary
alignment and error checks.
