Keyguard: Distinguish the TextView id of pinEntry

Both KeyguardSimPinView and KeyguardPinView have the same id of pinEntry
for their TextView of the password. When one of them is created in the
mSecurityViewContainer, the other one will get the wrong TextView of the
same id pinEntry.

Change the id pinEntry in KeyguardSimPinView to simPinEntry.
