x86, asm: Fix binutils 2.15 build failure

Add parentheses around one pushl_cfi argument.

Commit df5d1874 "x86: Use {push,pop}{l,q}_cfi in more places"
caused GNU assembler 2.15 (Debian Sarge) to fail. It is still
failing as of commit 07bd8516 "x86, asm: Restore parentheses
around one pushl_cfi argument". This patch solves build failure
with GNU assembler 2.15.
