Baruch Siach e00db162da net: stmmac: fix rx budget limit check 
[ Upstream commit fa02de9e75889915b554eda1964a631fd019973b ]

The while loop condition verifies 'count < limit'. Neither value change
before the 'count >= limit' check. As is this check is dead code. But
code inspection reveals a code path that modifies 'count' and then goto
'drain_data' and back to 'read_again'. So there is a need to verify
count value sanity after 'read_again'.

Move 'read_again' up to fix the count limit check.
