fmd: Fix problem in dynamic resource allocation algorithm
The patch that removed the forwarding optimized DPAA Ethernet driver
(and implicitly the Kconfig option CONFIG_FSL_DPAA_ETH_SG_SUPPORT and
all associated code) deleted the wrong branch of an #ifdef in the fmd
dynamic resource allocation algorithm.
As a result, the allocated FIFO size was not computed correctly,
causing resource depletion in case jumbo frames support is enabled.
