Unlock mUiccCard access in UiccProfile

Waiting on locks for the parent mUiccCard in the UiccProfile class has
the potential to cause deadlocks. Unlocking it is safe because
UiccCard#getCardState is read only, and EuiccCard#unregisterForEidReady
and #registerForEidReady are guarded within the RegistrantList class.

Bug: 78601499
