airo: work around stack usage warning
gcc-11 with KASAN on 32-bit arm produces a warning about a function
that needs a lot of stack space:
drivers/net/wireless/cisco/airo.c: In function 'setup_card.constprop':
drivers/net/wireless/cisco/airo.c:3960:1: error: the frame size of 1512 bytes is larger than 1400 bytes [-Werror=frame-larger-than=]
Most of this is from a single large structure that could be dynamically
allocated or moved into the per-device structure. However, as the callers
all seem to have a fairly well bounded call chain, the easiest change
is to pull out the part of the function that needs the large variables
into a separate function and mark that as noinline_for_stack. This does
not reduce the total stack usage, but it gets rid of the warning and
requires minimal changes otherwise.
