iwlwifi: Fix -EIO error code that is never returned

[ Upstream commit c305c94bdc18e45b5ad1db54da4269f8cbfdff6b ]

Currently the error -EIO is being assinged to variable ret when
the READY_BIT is not set but the function iwlagn_mac_start returns
0 rather than ret. Fix this by returning ret instead of 0.
