Ryan Lee 1a6dddad95 apparmor: ensure WB_HISTORY_SIZE value is a power of 2 
[ Upstream commit 6c055e6256 ]

WB_HISTORY_SIZE was defined to be a value not a power of 2, despite a
comment in the declaration of struct match_workbuf stating it is and a
modular arithmetic usage in the inc_wb_pos macro assuming that it is. Bump
WB_HISTORY_SIZE's value up to 32 and add a BUILD_BUG_ON_NOT_POWER_OF_2
line to ensure that any future changes to the value of WB_HISTORY_SIZE
respect this requirement.

Fixes: 136db99485 ("apparmor: increase left match history buffer size")
