arm64: Reinit free_idx to 1 in mmu_init

If mmu_init is called more than once then, free_idx should be reset to
    1. Here, the assumption would be that mmu_init will not be called more than
    once. However, this is not necessarily true. Thus, free_idx should be reset to 1
    every time we are initializing ttb from scratch.

BUG=None
    BRANCH=None
    TEST=Compiles sucessfully and boots to kernel
