fix flash bank auto_probe() fail with multiple targets 

get_flash_bank_by_addr() iterates through all flash banks
trying to auto_probe() every bank, even if bank can belongs to
target other than requested, and this other target can be
in non-halted state, which leads to error message and
operation abort.
  Same situation in gdb_new_connection() and gdb_memory_map():
get_flash_bank_by_num() tries to auto_probe() requested bank,
so first get bank by get_flash_bank_by_num_noprobe(), check
if it belongs to current connection's target and skip
get_flash_bank_by_num() (actually autoprobing) if not.
