msgb_alloc_headroom: Change size args to be uint16_t

Underlaying APIs (msgb_alloc) use a uint16_t as a type, which means
until now passing a value > 2^16 would succeed providing a msgb with
less space than requested.

Since those are static inline, there's no symbols used by apps, so we
should be safe enough changing the type to be uint16_t, since change
would only be applied at re-compile time.
