mm/mlock.c: reorganize mlockall() return values and remove goto-out label
In mlockall syscall wrapper after out-label for goto code just doing return. Remove goto out statements and return error values directly. Also instead of rewriting ret variable before every if-check move returns to 'error'-like path under if-check. Objdump asm listing showed me reducing by few asm lines. Object file size descreased from 220592 bytes to 220528 bytes for me (for aarch64).
