With commit b6664ba42f14 ("s390, kexec_file: drop arch_kexec_mem_walk()"),
we introduced the KEXEC_BUF_MEM_UNKNOWN macro. If kexec_buf.mem is set
to this value, kexec_locate_mem_hole() will try to allocate free memory.While other arch(s) like s390 and x86_64 already use this macro to initialize kexec_buf.mem with, arm64 uses an equivalent value of 0. Replace it with KEXEC_BUF_MEM_UNKNOWN, to keep the convention of initializing 'kxec_buf.mem' consistent across various archs.
