e1000: fix return value not set on error

Browse Source 
Dean noticed that 'err' wasn't being set when the "goto err_dma"
statement is executed in the following hunk from the commit. It's value
will be zero as a result of a successful call to e1000_init_hw_struct().

This patch changes the error condition to be correctly propagated.
