bdev/raid: Check if required params are specified when parsing .INI config file

Browse Source 
Checking if required parameters strip_size, num_base_bdevs, and
raid_level had been done in raid_bdev_config_add(). However, this
required us to use integer type.

If we do the check in raid_bdev_parse_raid(), we will be able to
use the same type between function parameters and variables of
struct, and hence do in this patch.

This will align with the next patch.
