hw/block/nvme: improve invalid zasl value reporting

The Zone Append Size Limit (ZASL) must be at least 4096 bytes, so
improve the user experience by adding an early parameter check in
nvme_check_constraints.

When ZASL is still too small due to the host configuring the device for
an even larger page size, convert the trace point in nvme_start_ctrl to
an NVME_GUEST_ERR such that this is logged by QEMU instead of only
traced.
