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.
