Cannot delete single SDC mapping if mappedToAll is True

[swevm]

Is not possible to remove a single mapping for a Volume if it have been mapped to all SDCs.
Not sure if this should be considered a bug or by design in SIO.

workaround:

• Get list of all SDCs
• Remove the SDC you want to unmap from the list
• Map volume to list of SDCs
• Change map_to_all_sdc parameter for volume to False

Not sure if this fixes the problem. Might cause a glitch for IO during unmap/remap. Need to test before implement
