arm64: errata: use KBUILD_CFLAGS_MODULE for erratum #843419

Browse Source 
commit b6dd8e0719 upstream.

Commit df057cc7b4 ("arm64: errata: add module build workaround for
erratum #843419") sets CFLAGS_MODULE to ensure that the large memory
model is used by the compiler when building kernel modules.

However, CFLAGS_MODULE is an environment variable and intended to be
overridden on the command line, which appears to be the case with the
Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.
