cxl/memdev: Fix firmware upload exact-fit handling
cxl_fw_prepare() classifies a firmware image as a one-shot transfer
only when its Transfer FW input payload is smaller than the mailbox
payload size. An image that exactly fills the payload is therefore
treated as a multi-part transfer.
The firmware loader invokes cxl_fw_write() only once for that image.
Since both offset == 0 and remaining == 0, the multi-part action
selection sends INITIATE, never sends END, and then attempts to activate
the target slot.
Include equality in the one-shot classification so exact-fit images use
the FULL action.
