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.
