x86: mtrr fix debug boot parameter

while looking at:

  http://bugzilla.kernel.org/show_bug.cgi?id=11541



I realized that the mtrr.show param cannot work, because
the code is processed much too early.

This patch:
 - Declares mtrr.show as early_param
 - Stays consistent with the previous param (which I doubt
   that it ever worked), so mtrr.show=1 would still work
 - Declares mtrr_show as initdata
