dm-writecache: Reduce metadata memory use by 8 bytes per cache block
wc_entry.index removed: This can be computed by pointer arithmetic
without storage.
wc_entry.age reduced to 32 bits: It only needs to be big enough to hold
max_age, which is limited to well below 32-bit range.
Reduces wc_entry size from 56 bytes to 48 bytes (from 72 to 64 bytes if
DM_WRITECACHE_HANDLE_HARDWARE_ERRORS enabled).
