nand/onenand: Fix missing argument checking for "markbad" command
The "nand markbad" and "onenand markbad" commands did not check if an
argument was passed; if this was forgotten, no error was raised but
block 0 was marked as bad.
While fixing this bug, clean up the code a bit and allow to pass more
than one block address, thus allowing to mark several blocks as bad
in a single command invocation.
