smb-lib: reset SDP draw to 100mA

The driver could leave SDP's current draw to a higher value
once its removed. This is because the code to reset the
current limit needs the type to be SDP to reset it which is
not going to be the case after removal.

So reset SDPs current limit back to 100mA in the code path
for non-SDP chargers.
