[PATCH v3 2/2] read-cache: use istate->repo for trace2 logging

["Jayesh Daga via GitGitGadget" <gitgitgadget@gmail.com>]

From: Jayesh Daga <jayeshdaga99@gmail.com>

trace2 calls in read-cache.c use the global 'the_repository',
even though the relevant index_state provides an explicit
repository pointer via 'istate->repo'.

Using the global repository can result in incorrect trace2
output when multiple repository instances are in use, as
events may be attributed to the wrong repository.

Use 'istate->repo' instead to ensure correct repository
attribution.
