[PATCH] bfa: remove VLA

[Stephen Kitt]

In preparation to enabling -Wvla, remove VLAs and replace them with
fixed-length arrays instead.

bfad_bsg.c uses a variable-length array declaration to measure the
size of a putative array; this can be replaced by the product of the
size of an element and the number of elements, avoiding the VLA
altogether.

This was prompted by https://lkml.org/lkml/2018/3/7/621
