nfs: Use proper enum definitions for nfs_show_stable
Commit 8224b2734ab1 ("NFS: Add static NFS I/O tracepoints") had a hack to work around some odd behavior observed with __print_symbolic. I couldn't ever get it to display NFS_FILE_SYNC when using TRACE_DEFINE_ENUM macros to set up the enum values. I tracked down the actual bug that forced me to add the workaround. That issue will be addressed soon, so replace the hack with a proper implementation.
