rtems-debugger-target.c: Dereference before null check spotted by Coverity

[Ryan Long]

CID 1468682: swbreaks is assigned a value dereferenced from target before it has been verified that target is not null.

173  rtems_debugger_target*         target = rtems_debugger->target;
   deref_ptr: Directly dereferencing pointer target.
174  rtems_debugger_target_swbreak* swbreaks = target->swbreaks.block;
175  size_t                         swbreak_size;
176  uint8_t*                       loc = (void*) addr;

   CID 1468682 (#1 of 1): Dereference before null check (REVERSE_INULL)check_after_deref: Null-checking target suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
180  if (target == NULL || swbreaks == NULL || kind != target->breakpoint_size) {
181    errno = EIO;
182    return -1;
