Define LWIP_CHKSUM_COPY_ALGORITHM when port provides LWIP_CHKSUM_COPY macro

Browse Source 
When the port has LWIP_CHECKSUM_ON_COPY enabled and provides
a definition of LWIP_CHKSUM_COPY, the existing logic left
LWIP_CHKSUM_COPY_ALGORITHM undefined

In this case we want it to be defined to 0 since none of the copy
checksum algorithms provided are being used

This commit also introduces indentation matching LWIP_CHKSUM to
improve the readability of the code
