Gustavo A. R. Silva 7a7f112833 ARM: OMAP2+: Fix -Warray-bounds warning in _pwrdm_state_switch() 
commit 847fb80cc0 upstream.

If function pwrdm_read_prev_pwrst() returns -EINVAL, we will end
up accessing array pwrdm->state_counter through negative index
-22. This is wrong and the compiler is legitimately warning us
about this potential problem.

Fix this by sanity checking the value stored in variable _prev_
before accessing array pwrdm->state_counter.

Address the following -Warray-bounds warning:
arch/arm/mach-omap2/powerdomain.c:178:45: warning: array subscript -22 is below array bounds of 'unsigned int[4]' [-Warray-bounds]
