pxe: Ensure we don't overflow bootargs
On a couple of platforms I've tripped over long PXE append lines overflowing
this array, due to having CONFIG_SYS_CBSIZE == 256. When doing preseeded Debian
installs it's pretty trivial to exceed that.
Since the symptom can be a silent hang or a crash add a check. Of course the
affected boards would also need an increased CBSIZE to actually work.
Note that due to the printing of the final bootargs string CONFIG_SYS_PBSIZE
also needs to be sufficiently large.
