kexec: fix omitting offset in extended crashkernel syntax
Setting
"crashkernel=512M-2G:64M,2G-:128M"
does not work but it turns to work if it has a trailing-whitespace,
like
"crashkernel=512M-2G:64M,2G-:128M ".
It was because of a bug in the parser, running over the cmdline.
This patch adds a check of the termination.
