Catalin Marinas ac7f207866 arm64: Do not pass tagged addresses to __is_lm_address() 
commit 91cb2c8b072e00632adf463b78b44f123d46a0fa upstream.

Commit 519ea6f1c82f ("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.

Fixes: 519ea6f1c82f ("arm64: Fix kernel address detection of __is_lm_address()")
