[PATCH 3/3] esrt.c: fix uninitialized use of 'fwversion' warning

[Erico Nunes]

This warning shows up with different gcc versions, and may become a
problem due to the use of -Werror:

  uefi/esrt/esrt.c: In function ‘check_entries’:
  uefi/esrt/esrt.c:84: error: ‘fwversion’ may be used uninitialized in this
  function

The warning seems to point to what potentially can be a bug. So, just
initialize fwversion to a safe value to fix it.

This has been built and tested with gcc 6.2.1, gcc 4.8.5 and gcc 4.4.7.
