ixgbe: Fix an error handling path in ixgbe_read_iosf_sb_reg_x550() 

All error handling paths, except this one, go to 'out' where
release_swfw_sync() is called.
This call balances the acquire_swfw_sync() call done at the beginning of
the function.

Branch to the error handling path in order to correctly release some
resources in case of error.
