[PATCH 4/7] lib: fwts_pipeio: remove redundant initializations of file to NULL

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The open assigns file to the open descriptor, so no need to initialize
it to NULL.  Cleans up 2 cppcheck style warnings:

src/lib/src/fwts_pipeio.c:397: (style) Variable 'file' is reassigned a
  value before the old one has been used.
src/lib/src/fwts_pipeio.c:429: (style) Variable 'file' is reassigned a
  value before the old one has been used
