kbuild: handle old pahole more gracefully when generating BTF
When CONFIG_DEBUG_INFO_BTF is enabled but available version of pahole is too old to support BTF generation, build script is supposed to emit warning and proceed with the build. Due to using exit instead of return from BASH function, existing handling code prematurely exits exit code 0, not completing some of the build steps. This patch fixes issue by correctly returning just from gen_btf() function only.
