[PATCH net 3/6] bnxt_en: Fix handling FRAG_ERR when NVM_INSTALL_UPDATE cmd fails

[Michael Chan]

From: Vasundhara Volam <vasundhara-v.vo...@broadcom.com>

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.")
