[PATCH v2 2/3] wifi: mwifiex: Replace one-element array with flexible-array member in struct mwifiex_ie_types_rxba_sync

["Gustavo A. R. Silva" <gustavoars@kernel.org>]

One-element and zero-length arrays are deprecated. So, replace
one-element array in struct mwifiex_ie_types_rxba_sync with
flexible-array member, and refactor the rest of the code, accordingly.

This results in no differences in binary output.
