Fix a possible null pointer derefernce:
The pointer returned by pxDuplicateNetworkBufferWithDescriptor()
was being dereferenced outside its null checks.
This could only happen if ipconfigZERO_COPY_TX_DRIVER was enabled.
Conveniently, the statement that used the pointer could be moved
into the scope of the null check.
