affs: struct affs_head: Replace 1-element array with flexible array

AFFS uses struct affs_head's "table" array as a flexible array. Switch
this to a proper flexible array[1]. There are no sizeof() uses; struct
affs_head is only ever uses via direct casts. No binary output
differences were found after this change.
