Revert "x86: kmsan: sync metadata pages on page fault"
This reverts commit 3f1e2c7a9099c1ed32c67f12cdf432ba782cf51f.
As noticed by Qun-Wei Lin, arch_sync_kernel_mappings() in
arch/x86/mm/fault.c is only used with CONFIG_X86_32, whereas KMSAN is only
supported on x86_64, where this code is not compiled.
The patch in question dates back to downstream KMSAN branch based on
v5.8-rc5, it sneaked into upstream unnoticed in v6.1.
