[PATCH] mm: memcg1: convert charge move flags to unsigned long long

[Roman Gushchin]

Currently MOVE_ANON and MOVE_FILE flags are defined as integers
and it leads to the following Smatch static checker warning:
    mm/memcontrol-v1.c:609 mem_cgroup_move_charge_write()
    warn: was expecting a 64 bit value instead of '~(1 | 2)'

Fix this be redefining them as unsigned long long.

Even though the issue allows to set high 32 bits of mc.flags
to an arbitrary number, these bits are never used, so it doesn't
have any significant consequences.
