      netfilter: nf_nat_sip: fix incorrect handling of EBUSY for RTCP expectation · 3f509c68

      We're hitting bug while trying to reinsert an already existing
      expectation:
      
      kernel BUG at kernel/timer.c:895!
      invalid opcode: 0000 [#1] SMP
      [...]
      Call Trace:
       <IRQ>
       [<ffffffffa0069563>] nf_ct_expect_related_report+0x4a0/0x57a [nf_conntrack]
       [<ffffffff812d423a>] ? in4_pton+0x72/0x131

       [<ffffffffa00ca738>] ? ip_nat_sdp_media+0x185/0x185 [nf_nat_sip]
      
      We have to remove the RTP expectation if the RTCP expectation hits EBUSY
      since we keep trying with other ports until we succeed.
