[PATCH] Correct formatting of gcry_mac_get_algo_keylen documentation

[Dmitry Eremin-Solenikov]

* doc/gcrypt.texi: add braces near gcry_mac_get_algo_keylen
  documentation.

Use braces around unsigned int in gcry_mac_get_algo_keylen
documentation, otherwise texinfo breaks that and uses 'int' as a
function definition.
