[PATCH v4 0/2] Fix issues reported by klocwork

[Aleksei Gimbitskii]

The klocwork static code analyzer found 11 critical issues and 7 error
issues in GVT-g source code. After the analyzation, one critical issue
and 6 "errors" was concluded as harmless. This patchset fixes other
cases, which might cause potential issues in future.

v4:
- Minor changes to one error message in patch 1. (Colin Xu) 
- After discusion we agreed that patch 2 remains unmodified.

v3:
- Remove typedef and let the enumeration starts from zero. (Zhi Wang)

V2:
- Print some error messages if page table type is invalid. (Colin Xu)
- Increase the size of the buffer. (Colin Xu)
- Initialize fb_info.obj in vgpu_get_plane_info(). (Colin Xu)

Aleksei Gimbitskii (2):
  drm/i915/gvt: Check if cur_pt_type is valid
  drm/i915/gvt: Assign NULL to the pointer after memory free.
