ixgbe: avoid redundant call to ixgbe_non_sfp_link_config()

ixgbe_non_sfp_link_config() is called twice in ixgbe_open()
once to assign its return value to err and again in the
conditional check. This patch uses the stored err value
instead of calling the function a second time. This avoids
redundant work and ensures consistent error reporting.

Also fix a small typo in the ixgbe_remove() comment:
"The could be caused" -> "This could be caused".
