[PATCH v3 11/17] stmmac: set dirty index out of the loop

[Alexandre TORGUE]

From: Giuseppe Cavallaro <peppe.cavall...@st.com>

The dirty index can be updated out of the loop where all the
tx resources are claimed. This will help on performances too.
Also a useless debug printk has been removed from the main loop.
