drivers/net/wireless/iwlwifi/iwl-agn.c: Fix return value from an unsigned function
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:
