Don't update target_dcache if it is not initialized
After previous patch, 'target_dcache' is initialized lazily. It is possible that 'target_dcache' is still NULL when GDB writes to memory. In this case, update to 'target_dcache' can be skipped. gdb: 2013-11-20 Yao Qi <yao@codesourcery.com> * target.c (memory_xfer_partial_1): Update 'target_dcache' if it is initialized.
