UBI: fastmap: Pass to_be_tortured when reusing old fastmap PEBs

In ubi_update_fastmap(), when no fresh PEB is available to replace an
old fastmap PEB, the old PEB is reused by erasing it synchronously
via ubi_sync_erase() with the torture flag hardcoded to zero.

However, old_fm->to_be_tortured[] may be non-zero: it is set during
fastmap scanning when ubi_io_read_data()/ubi_io_read_ec_hdr() reports
UBI_IO_BITFLIPS, meaning the PEB showed signs of bit decay and should
be tortured to verify it is still reliable.

When the old PEB is instead returned to the WL sub-system via
ubi_wl_put_fm_peb(), the to_be_tortured flag is honored. The
synchronous reuse path is inconsistent: it silently skips the torture
test for PEBs that exhibited bit-flips.

Fix it by passing &old_fm->to_be_tortured[i] to ubi_sync_erase().
