openzfs: fix gcc kernel module builds
Hi Ryan,
This is listed as "openzfs", but the vast majority of it is in dtrace...?
-Ravi (rpokala@)
- Suppress -Wredundant-decls. Ultimately this warning is harmless in
any case, and it does not look like there is a simple way to avoid
redundant declarations in this case without a lot of header pollution
(e.g. having openzfs's shim param.h pulling in sys/kernel.h for hz).
- Suppress -Wnested-externs, which is useless anyway.
Unfortunately it was not sufficient just to modify OPENZFS_CFLAGS,
because the warning suppressions need to appear on the command line
after they are explicitly enabled by CWARNFLAGS from sys/conf/kern.mk,
but OPENZFS_CFLAGS get added before due to use of -I for the shims.
