RDMA/cma: Fix truncation compilation warning in make_cma_ports

Browse Source 
commit 18126c767658ae8a831257c6cb7776c5ba5e7249 upstream.

The following compilation error is false alarm as RDMA devices don't
have such large amount of ports to actually cause to format truncation.

drivers/infiniband/core/cma_configfs.c: In function ‘make_cma_ports’:
drivers/infiniband/core/cma_configfs.c:223:57: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
  223 |                 snprintf(port_str, sizeof(port_str), "%u", i + 1);
      |                                                         ^
drivers/infiniband/core/cma_configfs.c:223:17: note: ‘snprintf’ output between 2 and 11 bytes into a destination of size 10
  223 |                 snprintf(port_str, sizeof(port_str), "%u", i + 1);
