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.
