Bugfix/cldsrv 533

[williamlardier]

Fixes a limitation during a corner case, when restoring an object within account/bucket with enabled exceeded quota:

• First, we reserve space when processing RestoreObject
• When the data is being actually restored, the cold backend will PUT the object tot he HOT location (with a specific header, x-scal-s3-version-id). But then tries to increase the inflights: in this case, if the quota is exceeded already, or the bytes are near to the limit, we fail, even if the space was reserved.

This PR introduces a way to detect DMF calls (the specific header) and, in this case, only check the quotas, without increasing the in-flights.

is this really needed?

Suggested change

	// withVersionId cover cases when an object is being restored with a specific version ID.
	// In this case, the storage space was already accounted for when the RestoreObject API call
	// was made, so we don't need to add any inflight, but quota must be evaluated.
	if (!checkQuota && !withVersionId) {
	if (!checkQuota) {

Indeed, it had been removed (and squashed)
