[PATCH] x86/boot: clean up whitespace in a20.c (v2)

[Harry Fellowes <harryfellowes1@gmail.com>]

This version fixes indentation problems introduced in the previous patch
while still removing trailing whitespace only.

Apologies for the previous version which seemed to have accidentally removed
indentation on several lines.
