Fix read and write register blocks in gdbstub
Previously, the padding wasn't correctly accounted for which caused the gdbstub to read and write everything after R15 (starting with the dummy FPA registers) incorrectly, which caused CPSR to not be handled correctly. Everything appears to be working as expected with this change.
