RDMA/bnxt_re: Fix clang -Wimplicit-fallthrough in bnxt_re_handle_cq_async_error()

Clang warns (or errors with CONFIG_WERROR=y):

  drivers/infiniband/hw/bnxt_re/main.c:1114:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
   1114 |         default:
        |         ^
  drivers/infiniband/hw/bnxt_re/main.c:1114:2: note: insert 'break;' to avoid fall-through
   1114 |         default:
        |         ^
        |         break;
  1 error generated.

Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.
