[Filestore] should not hang if a Forget request is received before fuse_init

[SvartMetal]

Notes

Follow-up for #4283.

A "Forget" request is not completed if it is received before fuse_init, because the FUSE handler cannot be called in this case

AI Review Summary

Verdict: ✅ No critical issues found

Critical issues

No critical issues found.

Other findings

• Minor | High: Commenting out fuse_reply_none creates an implicit contract that all consumers of virtiofsd/static must provide their own implementation — cloud/contrib/virtiofsd/fuse_lowlevel.c:361
• Minor | Medium: The cloud/contrib/virtiofsd/dynamic library target may fail to build or have runtime issues with the now-unresolved fuse_reply_none symbol — cloud/contrib/virtiofsd/dynamic/ya.make
• Nit | High: Unrelated test cleanup (default timer parameter removal) bundled with the bug fix — cloud/filestore/libs/vfs_fuse/fs_ut.cpp:3124
