[PATCH 7/7] arm: omap2: clksel: fix compile warning

[Felipe Balbi]

Fix the following compile warning:
arch/arm/mach-omap2/clkt_clksel.c: In function '_get_div_and_fieldval':
arch/arm/mach-omap2/clkt_clksel.c:100:35: warning: 'max_clkr' may be
used uninitialized in this function

While at that, also add a check to avoid using max_clkr while NULL.
