[PATCH 3/8] block: refresh bs->total_sectors on reopen

[Paolo Bonzini <pbonzini@redhat.com>]

After reopening a BlockDriverState, it's possible that the size of the
underlying file has changed.  This for example is covered by test 171.

Right now, this is handled by the raw driver's has_variable_length = true
setting.  Since this will be removed by the next patch, handle it on
reopen instead, together with the existing bdrv_refresh_limits.
