[Crash-utility] [PATCH] Remove lkcd_speedo() output spinner

[Sam Watters]

This patch removes the lkcd_speedo() function and its use.

The lkcd_speedo() function produces a 'spinner' in output when crash is
busy processing kernel crash dump files. The spinner makes the output of
crash commands unpredictable and complicates the parsing of output.
