[PATCH][next] net: stmmac: replace redundant comparison with true

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The comparison of the u32 variable queue with <= zero is always true
since an unsigned can never be negative. Replace the conditional
check with the boolean true to simplify the code.  The while loop
will terminate because of the zero check on queue before queue is
decremented.

Addresses-Coverity: ("Unsigned compared against 0")
