gdb_server: fix segfault with GDB command 'flash-erase'

Running the GDB command 'flash-erase' triggers sending the remote
GDB commands 'vFlashErase' (one per flash bank) followed by one
single 'vFlashDone', with no 'vFlashWrite' commands in between.
This causes the field 'gdb_connection->vflash_image' to be NULL
during the execution of 'vFlashDone', triggering a segmentation
fault in OpenOCD.

While parsing 'vFlashDone', check if any image to flash has been
received.
