ntfs: allow index root relocation

Browse source

Allow a resident attribute record to move to an extent MFT record when the
base record needs room for an attribute list. Retry the root conversion
after creating the list, but do not relocate a root that is already
external.

Roll the root back to the base record if persisting the attribute list
fails, and free extent MFT records left empty by relocation or rollback.
Also preserve bitmap allocation errors in index operations.
