Remove Dead Code in eos_parse

[ericpassmore]

src/eos_parse.c:198:5: warning: Value stored to 'inLength' is never read [deadcode.DeadStores] inLength -= readFromBuffer;

[ericpassmore]

Removing inLength -= readFromBuffer; it is never read. From function below.

eos_parse.c:parseStringField(uint8_t *in, uint32_t inLength, const char fieldName[], actionArgument_t *arg, uint32_t *read, uint32_t *written)

[ericpassmore]

From looking at the code the inLength is not needed because fieldLength is used. This has been in place since the very first commit.

Note paseStringField called two times. First Instance

parseStringField(null, sizeof(null), "Parent", arg, &read, &written);

Second Instance

parseStringField(buffer, bufferLength, "Memo", arg, &read, &written);
