[PATCH RESEND 16/62] brd: remove "ramdisk_size" command line parameter

[Askar Safin]

It was used mostly for initrd. It could be used only if
brd is built-in. Use "brd.rd_size" instead

-This option instructs the kernel to set up a ramdisk of the given

-passed by bootstrap! In this case, the size is selected automatically
