[10.6.X] Fix simulation of the pixel bad components on the FED channel basis for PreMixing

[mmusich]

backport of #27912

PR description:

During the CMSSW_11_0_0_pre5 validation it was noticed that the per-FED channel Pixel bad components handling (a.k.a. "stuck-TBM" simulation) introduced in PR #25466, was not working in the premixing case (cf. valDB report ).
This PR fixes the premixing case.

PR validation:

PR validation has been carried out by @tsusa by comparing the pixel valid hit occupancy maps in the baseline CMSSW_11_0_X branch for premixing with and without this PR and compared with classical mixing (tested earlier to work correctly).
I report here one example for BPix Layer 1:

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
