nvme-pci: add NVME_QUIRK_NO_DEEPEST_PS quirk for SOLIDIGM P44 Pro

[ Upstream commit e765bf89f42b5c82132a556b630affeb82b2a21f ]

This commit adds the NVME_QUIRK_NO_DEEPEST_PS quirk for device
[126f:2262], which belongs to device SOLIDIGM P44 Pro SSDPFKKW020X7

The device frequently have trouble exiting the deepest power state (5),
resulting in the entire disk being unresponsive.

Verified by setting nvme_core.default_ps_max_latency_us=10000 and
observing the expected behavior.
