RDMA/ucaps: Avoid format-security warning

Passing a non-literal format string to dev_set_name causes a warning:

drivers/infiniband/core/ucaps.c:173:33: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
  173 |         ret = dev_set_name(&ucap->dev, ucap_names[type]);
      |                                        ^~~~~~~~~~~~~~~~
drivers/infiniband/core/ucaps.c:173:33: note: treat the string as an argument to avoid this
  173 |         ret = dev_set_name(&ucap->dev, ucap_names[type]);
      |                                        ^
      |                                        "%s",

Turn the name into the %s argument as suggested by gcc.
