arm64: Silence clang warning on mismatched value/register sizes

[ Upstream commit: 27a22fbd ]

Clang reports a warning on the __tlbi(aside1is, 0) macro expansion since
the value size does not match the register size specified in the inline
asm. Construct the ASID value using the __TLBI_VADDR() macro.

Fixes: 222fc0c8 ("arm64: compat: Workaround Neoverse-N1 #1542419 for compat user-space")
