We will create this sort of identity mapping as follows:
If the gfn space is unoccupied, we just set the mapping. If the space
is already occupied by 1:1 mappings, do nothing. Failed for any
other cases.
"If space is already occupied by desired identity mapping, do nothing.
Otherwise, failure is returned."

"Cannot setup identity map, ..., gfn already mapped to..."
Fixed.
