arm64: Fix typo in the pmdp_huge_get_and_clear() definition
commit 911f56eeb87ee378f5e215469268a7a2f68a5a8a upstream.
With hardware AF/DBM support, pmd modifications (transparent huge pages)
should be performed atomically using load/store exclusive. The initial
patches defined the get-and-clear function and __HAVE_ARCH_* macro
without the "huge" word, leaving the pmdp_huge_get_and_clear() to the
default, non-atomic implementation.
Fixes: 2f4b829c625e ("arm64: Add support for hardware updates of the access and dirty pte bits")
