pc-bios/s390-ccw: El Torito 16-bit boot image size field workaround
Because of El Torito spec flaw boot image size needs to be verified.
Boot catalog entry size field has 16-bit width, and specifies size
in 512-byte units.
Thus, boot image size cannot exceed 32M.
We actually search for the file to get the file size.
This is done by scanning the ISO directory tree for the ISO block number
and reading the file size from the directory entry.
