cbm_validate() receives a pointer to the variable that will be
initialized with a validated capacity bitmask. The pointer points to a
variable of type unsigned long that is immediately assigned to a
variable of type u32 by the caller on return from cbm_validate().
Let cbm_validate() initialize a variable of type u32 directly.
At this time also change tha variable name "data" within parse_cbm() to
a name more reflective of the content: "cbm_val". This frees up the
generic "data" to be used later when it is indeed used for a collection
of input.
