From: "Michael J. Ruhl" <michael.j.ruhl@intel.com>

[ Upstream commit 5da9e742be44d9b7c68b1bf6e1aaf46a1aa7a52b ]

The module parameter num_user_context is defined as 'int' and
defaults to -1. The module_param_named() says that it is uint.

Correct module_param_named() type information and update the modinfo
text to reflect the default value.
