drivers/net/wireless/iwlwifi/iwl-agn.c: Fix return value from an unsigned functionmaster-2010-09-07

The function has an unsigned return type, but returns a negative constant
to indicate an error condition.  Another error condition in the same
function is indicated by returning 0, and indeed the only call to the
function checks for 0 to detect errors, so the return of a negative value
it converted to a return of 0.

A sematic match that finds this problem is as follows:

 unsigned f(...)
 { <+...
*  return -C;

// </smpl>
