[PATCH 2/6] rsi: remove redundant flash_content variable

[Siva Rebbagondla <siva8118@xxxxxxxxx>]

From: Siva Rebbagondla <siva.rebbagondla@xxxxxxxxxxxxxxxxxx>

while cleaning up the driver, observed that flash_content pointer is not
necessary in rsi_load_firmware(). Instead of this, driver can use
'fw_entry->data' directly.Hence, removed redundant flash_content pointer.
