[PATCH 11/12] relayfs: cleanup, change relayfs_file_* to relay_file_*

[Tom Zanussi <zanussi@us.ibm.com>]

This patch renames relayfs_file_operations to relay_file_operations,
and the file operations themselves from relayfs_XXX to relay_file_XXX,
to make it more clear that they refer to relay files.

Signed-off-by: Tom Zanussi <zanussi@us.ibm.com>
