[PATCH] nvmet: fix arbitration burst field mask

[James Fantin-Hardesty <james.fantin-hardesty@seagate.com>]

The Arbitration Burst (AB) field of the Arbitration feature is
CDW11 bits 2:0 (NVMe Base Specification 2.1, Feature 01h), but
nvmet incorrectly masks it with 0x3. Use 0x7 for both set and get.

Fixes: a0ed77d4c9a7 ("nvmet: Implement arbitration feature support")
