Subject: [PATCH][next] net: chelsio: remove unused function calc_tx_descs

The inlined helper function calc_tx_descs is not used and is redundant.
Remove it.

Cleans up clang scan build warning:
drivers/net/ethernet/chelsio/cxgb4/sge.c:814:28: warning: unused
function 'calc_tx_descs' [-Wunused-function]
