net: stmmac: ensure jumbo_frm error return is correctly checked for -ve value

[ Upstream commit 594238158bf748c285f0a73222cd9b7ccf3c525d ]

The current comparison of entry < 0 will never be true since entry is an
unsigned integer. Make entry an int to ensure -ve error return values
from the call to jumbo_frm are correctly being caught.
