Peter Xu e74465399c migration/multifd: Replace assert() with error_setg() in recv paths 
QPL and UADK multifd backends use assert() to validate wire-controlled
fields like per-page compressed lengths and packet size consistency.  These
asserts will stop working with -DNDEBUG builds, so may stop working.

Replace all assert() calls in the receive path with proper error_setg() so
validation failures are reported gracefully rather than crashing or
silently ignored.

While at it, touch up an assert() in qatzip recv path too.
