[PATCH v2] mctp: serial: replace memset with zero-initialization

[Manish Baing]

Use empty brace initialization (= {}) instead of explicit memset()
to zero-initialize stack memory to simplify the code.

No functional change.

Changes in v2:
- Fixed a compilation error caused by a duplicate variable declaration caught 
  by the kernel test robot.
