net/tftp.c: cosmetic: do not use assignment in if condition
This removes the following checkpatch issue: - ERROR: do not use assignment in if condition. There is one such error left: ERROR: do not use assignment in if condition #239: FILE: tftp.c:239: + if (!ProhibitMcast + && (Bitmap = malloc(Mapsize)) + && eth_get_dev()->mcast) { which would require an additional nested if to be fixed, resulting in longer and less readable code.
