fix trysetupdata when mAutoAttachOnCreation true

mAutoAttachOnCreation=true means that device can attach PS network
automatically. To do this, DCT should setup data call even PS is detached.
but when mAttached is false (PS detached) It blocks to setup data call
regardless of mAutoAttachOnCreation value. So changed to allow setup
data call when mAutoAttachOnCreation is true and mAttached is false.
