        kdump-lib: Introduce parse_kver_from_path() to get kernel version from its path name
    
        kdump_get_arch_recommend_crashkernel() expects the kernel version info,
        while _update_kernel() provides the absolute path, which contains the
        kernel version info.
    
        This patch introduce a dedicated function parse_kver_from_path() to
        extract the kernel info from the path
