[BugFix] Fix race condition issue in PrimaryIndex::memory_usage()

[sevev]

Why I'm doing:

There are two race condition issue when call function PrimaryIndex::memory_usage():

1. If rebuild primary index in apply compaction phase, we will clear primary index which is a read-write conflict with memory_usage().
2. If the memory is not enough, we may not load all bloom filter of persistent index into memory but only load the shard we needed and there are some nullptr in _bf_vec. When we call function _memory_usage(), we will get nullptr exception.

What I'm doing:

Fix the bug.
