net: stmmac: fix a broken u32 less than zero check

The check that queue is less or equal to zero is always true
because queue is a u32; queue is decremented and will wrap around
and never go -ve. Fix this by making queue an int.

Detected by CoverityScan, CID#1428988 ("Unsigned compared against 0")
