exportfs: Replace zero-length array with DECLARE_FLEX_ARRAY() helper

Browse Source 
Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members instead. So, replace zero-length array
declaration in struct fid with the new DECLARE_FLEX_ARRAY()
helper macro.

This helper allows for a flexible-array member in a union.
