NFS4_CONTENT_DATA and NFS4_CONTENT_HOLE both only exist under NFS v4.2.
Move their corresponding TRACE_DEFINE_ENUM calls under this Kconfig
option.

This can be defined as simply an NFS4_INODE_EVENT() since we don't have
the name of a specific xattr to list. This roughly matches readdir,
which also uses an NFS4_INODE_EVENT() tracepoint.

These functions take similar arguments, and can share a tracepoint class
for common formatting.
