[XFS] kill unnessecary ioops indirection
Currently there is an indirection called ioops in the XFS data I/O path. Various functions are called by functions pointers, but there is no coherence in what this is for, and of course for XFS itself it's entirely unused. This patch removes it instead and significantly reduces source and binary size of XFS while making maintaince easier.
