PM/VFS protocol: prefix with VFS_PM_
These calls are sent to VFS, and thus should be prefixed with VFS_. Clean up the protocol and PM's main function a bit. Since the protocol is substantially big and different from normal VFS requests, this protocol retains its own numbering range for now. Change-Id: Ia62104b5c5c929ed787144816d2e4cc70bed3b0b
