MdeModulePkg/Core/Pei: set AprioriCount=0 before walking through next FV

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4438

The main dispatch loop in PeiDispatcher() goes through each FV and
calls DiscoverPeimsAndOrderWithApriori() to search Apriori file to
reorder all PEIMs then do the PEIM dispatched.

DiscoverPeimsAndOrderWithApriori() calculates Apriori file count for
every FV once and set Private->AprioriCount, but Private->AprioriCount
doesn't be set to 0 before dispatch loop walking through the next FV.

It causes the peim which sort on less than Private->AprioriCount and
depex is not satisfied would be dispatched when dispatch loop go through
to a scaned FV, even the peim is not set in APRIORI file.
