Dave Jiang 793a539ac7 cxl: Explicitly initialize resources when media is not ready
When media is not ready do not assume that the capacity information from
the identify command is valid, i.e. ->total_bytes
->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly
zero out the capacity resources and exit early.

Given zero-init of those fields this patch is functionally equivalent to
the prior state, but it improves readability and robustness going
forward.
