[LU-11409] only first 100 OSC can shrink grants

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.7
• Affects Version/s: Upstream
• Severity: 3
• Assignee: Alex Zhuravlev
• Reporter: Alex Zhuravlev

Description

the logic in osc_grant_work_handler() wants to limit number of shrink requests in flight,

but it doesn't take skipped OSCs into account, meaning only the first 100 OSCs are subject to this procedure.
