Dan Carpenter a56dcc6b45 net: cdc_ncm: Signedness bug in cdc_ncm_set_dgram_size() ...

This code is supposed to test for negative error codes and partial
reads, but because sizeof() is size_t (unsigned) type then negative
error codes are type promoted to high positive values and the condition
doesn't work as expected.
