iwlwifi: mvm: don't capture firmware coredump for D3->D0 reconfig
The code to capture firmware errors works during the reconfiguration
phase after an error. As the D3->D0 transition uses the same flow to
get the D0 image reconfigured, this triggered and caused a firmware
coredump to be collected. This in turn, if it isn't picked up by
userspace, can cause module unloading to fail, which is how the bug
was detected.
To fix this issue, introduce a new status flag (D3_RECONFIG) and use
it to detect that during reconfiguration no coredump should be taken
and reported.
