pnfs-obj: Return PNFS_NOT_ATTEMPTED in case of read/write_pagelist
objlayout driver was always returning PNFS_ATTEMPTED from it's
read/write_pagelist operations. Even on error. Fix that.
Start by establishing an error return API from io-engine, by
not returning ssize_t (length-or-error) but returning "int"
0=OK, 0>Error. And clean up all return types in io-engine.
Then if io-engine returned error return PNFS_NOT_ATTEMPTED
to generic layer. (With a dprint)
