[PATCH 5.15 504/913] RDMA/irdma: Remove incorrect masking of PD

[Greg Kroah-Hartman]

From: Mustafa Ismail <mustafa.ismail@xxxxxxxxx>

[ Upstream commit 17850f2b0b4b806e47cc44df94186bfc2cdd490b ]

The PD id is masked with 0x7fff, while PD can be 18 bits for GEN2 HW.
Remove the masking as it should not be needed and can cause incorrect PD
id to be used.

Fixes: b48c24c2d710 ("RDMA/irdma: Implement device supported verb APIs")
