kernel: lib: allow larger stack frame size for KASan

Browse source 
Some functions consume more than allowed stack frame
size with KASan enabled and GCC warns it as an error.
To avoid compilation warning, allow larger stack frame
size when KASan is enabled instead of changing each file.

Below is one of the warning messages for reference.
kernel/net/wireless/nl80211.c: In function 'nl80211_send_wiphy':
kernel/net/wireless/nl80211.c:1705:1: warning: the frame size
of 5488 bytes is larger than 2048 bytes [-Wframe-larger-than=]
