[PATCH] arch/x86/boot/memory.c: Touched up coding-style issues

[Jordan Borgner]

Added missing parentheses to sizeof() function in detect_memory_e820().

Removed unnecessary braces in detect_memory_e801().

Replaced three if-statements with a ternary if-statement and 
removed an unnecessary integer variable in detect_memory().

This is my first patch I hope it is okay.
