nvme: respect NVME_QUIRK_DISABLE_WRITE_ZEROES when wzsl is set

The NVM Command Set Identify Controller data may report a non-zero
Write Zeroes Size Limit (wzsl). When present, nvme_init_non_mdts_limits()
unconditionally overrides max_zeroes_sectors from wzsl, even if
NVME_QUIRK_DISABLE_WRITE_ZEROES previously set it to zero.

This effectively re-enables write zeroes for devices that need it
disabled, defeating the quirk. Several Kingston OM* drives rely on
this quirk to avoid firmware issues with write zeroes commands.

Check for the quirk before applying the wzsl override.
