  In some cases we may not be freeing up memory allocated for certain
NVM commands because the code might have bailed out before reaching
rte_free(). This patch moves some code around to ensure the allocated
memory is freed before exiting the function.

Fixes: 19e6af01bb36 ("net/bnxt: support get/set EEPROM")
