kexec: fix OOPS in crash_kernel_shrink
Two "echo 0 > /sys/kernel/kexec_crash_size" OOPSes kernel. Also content
of this file is invalid after first shrink to zero: it shows 1 instead of
0.
This scenario is unlikely to happen often (root privs, valid crashkernel=
in cmdline, dump-capture kernel not loaded), I hit it only by chance.
This patch fixes it.
