[PATCH 13/35] MdeModulePkg: PEI Core: clean up "AprioriFile" handling in FindFileEx()

["Laszlo Ersek" <lersek@redhat.com>]

Clean up two issues around FindFileEx():

- The "AprioriFile" parameter's type differs between the function
  declaration and the function definition. The correct type is
  (EFI_PEI_FILE_HANDLE*).

- "FfsFileHeader" has type (EFI_FFS_FILE_HEADER*); for clarity, we should
  cast it explicitly to EFI_PEI_FILE_HANDLE when assigning it to
  (*AprioriFile).

This is a semantic cleanup, there is no functional change.

Notes:
    lightly tested: OVMF uses APRIORI PEI in the FDF files
