[PATCH] Bluetooth: btusb: Use DECLARE_FLEX_ARRAY() for qca_dump_hdr

[PATCH] Bluetooth: btusb: Use DECLARE_FLEX_ARRAY() for qca_dump_hdr

[Jeremy Dean]

Replace the deprecated zero-length array members in struct
qca_dump_hdr with DECLARE_FLEX_ARRAY(), since C99 flexible array
members are not permitted inside unions or as the sole member of
a struct.

Verified via offsetof()/sizeof() comparison that struct layout
(data/data0 offsets and overall size) is unchanged, and confirmed
the driver still compiles cleanly with the change.
