[PATCH] print memory in MB units in initrd-too-large errmsg

[Jim Cromie <jim.cromie@gmail.com>]

Change 2 error messages to display sizes in MB, not bytes.

qemu: initrd is too large, cannot support this. (max: 2047 MB, need 5833 MB)

Also, distinguish 2 sites by adding "it" and "this" respectively.
This tells a careful reader that the error above is from the 2nd size
check.

With MB displayed, I have to ask: is it coincidence that max == 2048-1 ?
