block/nvme: Use generic NvmeBar structure

Browse Source 
Commit f3c507adcd ("NVMe: Initial commit for new storage interface")
introduced the NvmeBar structure. Unfortunately in commit bdd6a90a9e
("block: Add VFIO based NVMe driver") we duplicated it.

Apparently in commit a3d9a352d4 ("block: Move NVMe constants to
a separate header") we tried to unify headers but forgot to remove
the structure declared in the block/nvme.c source file.

Do it now, and remove the structure size check which is redundant
with the header check added in commit 74e18435c0 ("hw/block/nvme:
Align I/O BAR to 4 KiB").
