[PATCH master 3/7] net: fec_mpc5200: fix false positive -Wmisleading-indentation

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

After the preprocessor runs, the code in question looks like this:
SDMA_INT_DISABLE

	while ((counter--) && (!(fec->eth->ievent & FEC_IEVENT_GRA)));
	{
	     struct mpc5xxx_sdma *sdma = (struct mpc5xxx_sdma *)MPC5XXX_SDMA;
	     sdma->IntMask |= (1 << tasknum);
	}

Which understandably looks like a bug. Avoid this by using do { } while
(0) and moving the semicolon to a separate line.
