i40e: remove redundant initialization of read_size 

Variable read_size is initialized and this value is never read, it is
instead set inside the do-loop, hence the initialization is redundant
and can be removed. Cleans up clang warning:

drivers/net/ethernet/intel/i40e/i40e_nvm.c:390:6: warning: Value stored
to 'read_size' during its initialization is never read
