Fix the location of "Setting variable MTRR" printk. 

Without that fix the debugging is harder because the person debugging
  coreboot will see the following twice(note the repeated MTRR number):
    Setting variable MTRR 0, base:    0MB, range: 4096MB, type WB
    [...]
    Setting variable MTRR 1, base: 4096MB, range:  512MB, type WB
    Setting variable MTRR 1, base: 4608MB, range:  256MB, type WB
    Setting variable MTRR 1, base: 3072MB, range: 1024MB, type UC
  instead of the following twice:
    Setting variable MTRR 0, base:    0MB, range: 4096MB, type WB
    [...]
    Setting variable MTRR 1, base: 3072MB, range: 1024MB, type UC

Thanks to kmalkki on #coreboot's Freenode IRC channel for the idea:
  May 25 23:57:17 <kmalkki>	I would add (move) that "Setting variable MTRR..." debug at the end of set_var_mtrrs()
