[PATCH v3 1/4] ref: initialize "fsck_ref_report" with zero

[shejialuo <shejialuo@gmail.com>]

In "fsck.c::fsck_refs_error_function", we need to tell whether "oid" and
"referent" is NULL. So, we need to always initialize these parameters to
NULL instead of letting them point to anywhere when creating a new
"fsck_ref_report" structure.

The original code explicitly initializes the "path" member in the
"struct fsck_ref_report" to NULL (which implicitly 0-initializes other
members in the struct). It is more customary to use " {0} " to express
that we are 0-initializing everything. In order to be align with the the
codebase, initialize "fsck_ref_report" with zero.
