int_osx_receive_prim() in gsm-fw/gpf/osx/osx.c: there was an error in the
reconstruction of this function from disassembly in the logic that implements
special handling for MPHC_RXLEV_REQ messages.
The code is now fixed to properly match what the binary object version does;
with this fix the firmware now performs the power measurement phase correctly
and the initial network registration succeeds.
