proc_sr: remove info log when starting SR proc

this was a very noisy log that was printed in pretty much
every TTI because the BSR procedure starts a SR whenever
it needs to send a regular BSR. The SR is canceled when a UL
grant arrives but the log line stays there.

Since we are printing a log when we actually signal a SR
to the PHY, this line is not needed.
