nfc: uapi: use kernel size_t to fix user-space builds

commit 79b69a83705e621b258ac6d8ae6d3bfdb4b930aa upstream.

Fix user-space builds if it includes /usr/include/linux/nfc.h before
some of other headers:

  /usr/include/linux/nfc.h:281:9: error: unknown type name ‘size_t’
    281 |         size_t service_name_len;
        |         ^~~~~~
