When the FW tells the driver to retry the INSTALL_UPDATE command after
it has cleared the NVM area, the driver is not clearing the previously
used ALLOWED_TO_DEFRAG flag. As a result the FW tries to defrag the NVM
area a second time in a loop and can fail the request.

Fixes: 1432c3f6a6ca ("bnxt_en: Retry installing FW package under NO_SPACE error condition.")
