vdpa/mlx5: Fix wrong use of bit numbers

stable inclusion
from stable-5.10.30
commit 253acf2e983b2730de16cb50a7c77a8af3b42dee
bugzilla: 51791

--------------------------------

[ Upstream commit 4b454a82 ]

VIRTIO_F_VERSION_1 is a bit number. Use BIT_ULL() with mask
conditionals.

Also, in mlx5_vdpa_is_little_endian() use BIT_ULL for consistency with
the rest of the code.
