skb: add some helpers for skb drop reasons
In order to simply the definition and assignment for
'enum skb_drop_reason', introduce some helpers.
SKB_DR() is used to define a variable of type 'enum skb_drop_reason'
with the 'SKB_DROP_REASON_NOT_SPECIFIED' initial value.
SKB_DR_SET() is used to set the value of the variable. Seems it is
a little useless? But it makes the code shorter.
SKB_DR_OR() is used to set the value of the variable if it is not set
yet, which means its value is SKB_DROP_REASON_NOT_SPECIFIED.
