wifi: carl9170: Fix multiple -Warray-bounds warnings
GCC (and Clang)[1] does not like having a partially allocated object,
since it cannot reason about it for bounds checking. Instead, fully
allocate struct carl9170_cmd.
Fix the following warnings Seen under GCC 13:
drivers/net/wireless/ath/carl9170/cmd.c:125:30: warning: array subscript ‘struct carl9170_cmd[0]’ is partly outside array bounds of ‘unsigned char[4]’ [-Warray-bounds=]
