hw/block/nvme: fix bad clearing of CAP

Browse source 
Commit 37712e00b1 ("hw/block/nvme: factor out pmr setup") changed the
control flow such that the CAP register is erronously cleared after
nvme_init_pmr() has configured it. Since the entire NvmeCtrl structure
is zero-filled initially, there is no need for the explicit clearing, so
just remove it.
