block: fine-granular CAP_SYS_ADMIN for Persistent Reservation
Allow of unprivileged Persistent Reservation operations on devices
if the write permission check on the device node has passed.
brw-rw---- 1 root disk 259, 0 Jun 13 07:09 /dev/nvme0n1
In the example above, the "disk" group of nvme0n1 is also allowed to
make reservations on the device even without CAP_SYS_ADMIN.
