[POWERPC] spufs: Handle errors in SPU coredump code, and support coredump to a pipe

Rework spufs_coredump_extra_notes_write() to check for and return errors.

If we're coredumping to a pipe we can't trust file->f_pos, we need to
maintain the foffset value passed to us. The cleanest way to do this is
to have the low level write routine increment foffset when we've
successfully written.
