[PATCH] sunrpc: rpc_debug and others are defined even if CONFIG_SUNRPC_DEBUG unset

[Ben Dooks <ben.dooks@codethink.co.uk>]

The rpc_debug, nfs_debug, nfsd_debug and nlm_debug are exported
even if CONFIG_SUNRPC_DEBUG is not set. This means that the
debug header should also define these to remove the following
sparse warnings:

net/sunrpc/sysctl.c:29:17: warning: symbol 'rpc_debug' was not declared. Should it be static?
net/sunrpc/sysctl.c:32:17: warning: symbol 'nfs_debug' was not declared. Should it be static?
net/sunrpc/sysctl.c:35:17: warning: symbol 'nfsd_debug' was not declared. Should it be static?
net/sunrpc/sysctl.c:38:17: warning: symbol 'nlm_debug' was not declared. Should it be static?
