migration/multifd: correct multifd_send_thread to trace the flags
The p->flags could be updated via the send_prepare callback, e.g. OR-ed
with MULTIFD_FLAG_ZLIB via zlib_send_prepare. Assign p->flags to the
local "flags" before the send_prepare callback could only get partial of
p->flags. Fix it by moving the assignment of p->flags to the local flags
after the callback, so that the correct flags can be traced.
Fixes: ab7cbb0b9a3b ("multifd: Make no compression operations into its own structure")
