change uneeded const

[sbruno]

Summary

another warning squash

[neel]

Wouldn't this create another warning at line 112 because 'devspec' is a const and is now assigned to a non-const variable?
np = (devspec + strlen(dv->dv_name));

[sbruno]

Instead of changing the qualifier on np to non-const, change the assignment of the pointer to cp
with a cast of np to remove the const. This lets the compiler know we looked at it.

[sbruno]

Conserve const qualifiers and cast the strtol() use

[neel]

Looks good.
