sfc: fix wrong tx channel offset with efx_separate_tx_channels
tx_channel_offset is calculated in efx_allocate_msix_channels, but it is also calculated again in efx_set_channels because it was originally done there, and when efx_allocate_msix_channels was introduced it was forgotten to be removed from efx_set_channels. Moreover, the old calculation is wrong when using efx_separate_tx_channels because now we can have XDP channels after the TX channels, so n_channels - n_tx_channels doesn't point to the first TX channel. Remove the old calculation from efx_set_channels, and add the initialization of this variable if MSI or legacy interrupts are used, next to the initialization of the rest of the related variables, where it was missing.
