Ayush Jain 2dcc0e4b3c selftests/mm: FOLL_LONGTERM need to be updated to 0x100
commit 1738b94962 upstream.

After commit 2c2241081f ("mm/gup: move private gup FOLL_ flags to
internal.h") FOLL_LONGTERM flag value got updated from 0x10000 to 0x100 at
include/linux/mm_types.h.

As hmm.hmm_device_private.hmm_gup_test uses FOLL_LONGTERM Updating same
here as well.

Before this change test goes in an infinite assert loop in
hmm.hmm_device_private.hmm_gup_test
