Subject: [PATCH] sh_eth: fix result of sh_eth_check_reset() on timeout

When  the first loop in sh_eth_check_reset() runs to its end, 'cnt' is 0, so the
following check for 'cnt < 0' fails to catch the timeout.  Fix the  condition in
this check, so that the timeout  is actually reported.
While at it, fix the grammar in the failure message...

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

---
The patch is against the David Miller's 'net.git' repo.
Dave, since this is fixing the failure case, I don't think it's needed in
-stable...
