Subject: [PATCH] net: phy: Fix overlong PHY timeout

Commit 27c3f70f3b50 ("net: phy: Increase link up delay in
genphy_update_link()") increased the per-iteration waiting time from
1ms to 50ms, without adjusting the timeout counter. This lead to the
timeout increasing from the typical 4 seconds to over three minutes.

Adjust the timeout counter evaluation by that factor of 50 to bring the
timeout back to the intended value.
