[SPARK-14131][SQL[STREAMING] Improved fix for avoiding potential deadlocks
in HDFSMetadataLog
## What changes were proposed in this pull request?
Current fix for deadlock disables interrupts in the StreamExecution which
getting offsets for all sources, and when writing to any metadata log, to avoid
potential deadlocks in HDFSMetadataLog(see JIRA for more details). However,
disabling interrupts can have unintended consequences in other sources. So I am
making the fix more narrow, by disabling interrupt it only in the
HDFSMetadataLog. This is a narrower fix for something risky like disabling
interrupt.
## How was this patch tested?
Existing tests.
