Remove duplicate Update_System_Details() function calls

Only run Update_System_Details on boot after decryption is
complete, if device is unencrypted, or if decryption prompt
is cancelled.

This significantly decreases the delay in reaching the
decryption prompt on devices with large used storage

Use refreshsizes action to update system details when
Cancel button is pressed at decryption prompt
