modpost: abort if module name is too long
Module name has a limited length, but currently the build system
allows the build finishing even if the module name is too long.
CC /root/kprobe_example/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz.mod.o
/root/kprobe_example/abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz.mod.c:9:2:
warning: initializer-string for array of chars is too long [enabled by default]
.name = KBUILD_MODNAME,
^
but it's merely a warning.
This patch adds the check of the module name length in modpost and stops
the build properly.
