Lora: Fix resetting of max_eirp and antenna_gain values (mbed-os 5.8 branch)

[kivaisan]

Description

This is a fix for issue #6391. Please note that this commit is only for mbed-os 5.8 branch. In master this issue no longer occurs due to PR #6279.

max_eirp and antenna_gain are floating point variables. Values of these
were incorrectly read from MIB as integer and therefore incorrect values
were set.

We are currently not taking directly to the release branch. We will take it from here, and add it manually to 5.8.1

@0xc0170 Please label this with 5.8.1

We are aware of this and take this manually as specified above once release candidate is created. Will get in

@AnttiKauppila To be more clear. The release script works on PRs that are already merged to master branch and creates patches from those which then go to the release-candidate branch along with all others tagged for the same release. A PR is then raised from the release-candidate to the release branch and that PR is tested in CI. As this cannot be merged directly to the release branch , tagging it would break the release script. We will thus have to deal with this manually.

Marked for 5.8.2 (@adbridge @cmonr ), once we run the script, this should be removed and cherry-picked. I checked 5.8.1, the commit was not propagated.
