ixgbevf: fix unused variable warning

The new ixgbevf_set_rx_buffer_len() function causes a harmless warnings
in configurations with large page size:

drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c: In function 'ixgbevf_set_rx_buffer_len':
drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c:1758:15: error: unused variable 'max_frame' [-Werror=unused-variable]

This rephrases the code so that the compiler can see the use of that
variable, making it slightly easier to read in the process.

Fixes: f15c5ba5b6cd ("ixgbevf: add support for using order 1 pages to receive large frames")
