[PATCH] mm/cma: remove stray newline from auto-generated CMA area name

[Hongfu Li]

From: Hongfu Li <lihongfu@xxxxxxxxxx>

When no name is supplied, cma_new_area() generates names with format
"cma%d\n", introducing an unintended newline character ('\n') in the
CMA name.

Most CMA regions are created with explicit names, so this path is
seldom hit. The newline only creates cosmetic noise in debug logs,
traces and debugfs with no functional impact.
