net: make snmp_mib_free static inline
Fengguang reported:
net/built-in.o: In function `in6_dev_finish_destroy':
(.text+0x4ca7d): undefined reference to `snmp_mib_free'
this is due to snmp_mib_free() is defined when CONFIG_INET is enabled,
but in6_dev_finish_destroy() is now moved to core kernel.
I think snmp_mib_free() is small enough to be inlined, so just make it
static inline.
