Catalin Marinas 91cb2c8b07 arm64: Do not pass tagged addresses to __is_lm_address() ...

Commit 519ea6f1c8 ("arm64: Fix kernel address detection of
__is_lm_address()") fixed the incorrect validation of addresses below
PAGE_OFFSET. However, it no longer allowed tagged addresses to be passed
to virt_addr_valid().

Fix this by explicitly resetting the pointer tag prior to invoking
__is_lm_address(). This is consistent with the __lm_to_phys() macro.
