NFS: convert call_sync() to a function

This patch changes nfs4_call_sync() from a macro into a
static inline function.  As a macro, the call_sync()
function will not do any type checking and depends
on the sequence arguments always having the same name.
As a function, we get to have type checking and can
rename the arguments if we so choose.
