mptcp: pm: drop match in userspace_pm_append_new_local_addr

Browse Source 
The variable 'match' in mptcp_userspace_pm_append_new_local_addr() is a
redundant one, and this patch drops it.

No need to define 'match' as 'struct mptcp_pm_addr_entry *' type. In this
function, it's only used to check whether it's NULL. It can be defined as
a Boolean one.

Also other variables 'addr_match' and 'id_match' make 'match' a redundant
one, which can be replaced by directly checking 'addr_match && id_match'.
