[PATCH] x86: Fix PTI comment in entry_SYSCALL_64

[Nadav Amit]

The comment is confusing since the path is taken when
PAGE_TABLE_ISOLATION is disabled (while the comment says it is not
taken).

x86/mm/pti: Fix PTI comment in entry_SYSCALL_64()

The comment is confusing since the path is taken when
CONFIG_PAGE_TABLE_ISOLATION=y is disabled (while the comment says it is not
taken).
