[PATCH] Fix wrong remove_parameter() calls

[Bernhard Walle]

When --reuse-cmdline is specified, kexec automatically removes some command
line parameter that are *known* to break the kexec'd target. That patch
corrects that behaviour:

 1. BOOT_IMAGE should be removed always when --reuse-cmdline is specified since
    it's likely that the kernel is not the same as the running kernel. As only
    lilo-like bootloaders (i.e. not GRUB) adds that parameter, there's no need
    to add a BOOT_IMAGE here.

 2. crashkernel should be only removed when 'kexec -p' is called. For the
    normal kexec, the crashkernel parameter can be passed as in the
    running kernel.

The mistake has been introduced by commit 3c5bb06948881b3e31c783c19edef74275794280
by myself.
