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.
