[patch V2 2/3] ShellPkg/Dp: Initialize summary date when run DP

[Dandan Bi <dandan.bi@intel.com>]

Issue:
When run "dp -s" or ("dp -v") command in shell several times,
the summary reuslts are different each time.

The root cause is that the previous global data "SummaryData"
is not cleaned when the dp command is callled next time.
This patch initializes the global data "SummaryData"
when the dp dymanic command is called.
