modpost: detect modules without a MODULE_LICENSE
Partially revert commit 2fa365682943 ("kbuild: soften MODULE_LICENSE
check") so that modpost detects modules that do not have a
MODULE_LICENSE.
Sam's commit also changed the fatal error to a warning, which I am
leaving as is.
This gives advance notice of when a module has no license and will taint
the kernel if the module is loaded.
This produces the following warnings on x86_64 allmodconfig:
