wifi: mwifiex: duplicate static structs used in driver instances
mwifiex_band_2ghz and mwifiex_band_5ghz are statically allocated, but
used and modified in driver instances. Duplicate them before using
them in driver instances so that different driver instances do not
influence each other.
This was observed on a board which has one PCIe and one SDIO mwifiex
adapter. It blew up in mwifiex_setup_ht_caps(). This was called with
the statically allocated struct which is modified in this function.
