cifs: map NT_STATUS_SHARING_VIOLATION to EBUSY instead of ETXTBSY
NT_SHARING_VIOLATION errors are mapped to ETXTBSY which is unexpected for operations such as unlink where we can hit these errors. The patch maps the error NT_SHARING_VIOLATION to EBUSY instead. The patch also replaces all instances of ETXTBSY in cifs_rename_pending_delete() with EBUSY.
