[ Upstream commit dd2ebf3404c7c295014bc025dea23960960ceb1a ]

If FW returns FRAG_ERR in response error code, driver is resending the
command only when HWRM command returns success. Fix the code to resend
NVM_INSTALL_UPDATE command with DEFRAG install flags, if FW returns
FRAG_ERR in its response error code.

Fixes: cb4d1d626145 ("bnxt_en: Retry failed NVM_INSTALL_UPDATE with defragmentation flag enabled.")
