[xfer] Generalise metadata "whence" field to "flags" field
iPXE has never supported SEEK_END; the usage of "whence" offers only
the options of SEEK_SET and SEEK_CUR and so is effectively a boolean
flag. Further flags will be required to support additional metadata
required by the Fibre Channel network model, so repurpose the "whence"
field as a generic "flags" field.
xfer_seek() has always been used with SEEK_SET, so remove the "whence"
field altogether from its argument list.
