IO Framework: use standard errno codes as return values
This patch redefines the values of IO_FAIL, IO_NOT_SUPPORTED and
IO_RESOURCES_EXHAUSTED to match the corresponding definitions in
errno.h:

    #define IO_FAIL                     (-ENOENT)
    #define IO_NOT_SUPPORTED            (-ENODEV)
    #define IO_RESOURCES_EXHAUSTED      (-ENOMEM)

NOTE: please note that the IO_FAIL, IO_NOT_SUPPORTED and
IO_RESOURCES_EXHAUSTED definitions are considered deprecated
and their usage should be avoided. Callers should rely on errno.h
definitions when checking the return values of IO functions.
