kgdbts: fix hw_access_break_test
The test for access watchpoints (hw_access_break_test) was broken
(always failed) because the compiler optimized out the write to the
static helper variable (hw_break_val2), as it is never read anywhere.
This resulted in the target variable (hw_break_val) not being accessed
and thus the breakpoint not being triggered.
Remove the helper variable (hw_break_val2), and use READ_ONCE to force
reading the target variable (hw_break_val).
