After rework settings will be no longer created dynamically
for each device so we need to make some fixups first.
* Use set_[ksettings,unmaskirq]() as a set function for
["keepsettings","unmaskirq"] setting.
* Allow writes to ["io_32bit","unmaskirq"] settings also when
drive->no_[io_32bit,unmask] is set (this is checked later inside
set_[io_32bit,unmaskirq]() anywyay and keeps consistency with
the corresponding HDIO_SET_[32BIT,UNMASKINTR] ioctls).
* Use max possible multi sectors value (16) as an allowed max for
"multcount" setting. set_multcount() set function checks against
device's max possbile value anyway and it makes the proc setting
consistent with the corresponding HDIO_SET_MULTCOUNT ioctl.
