[PATCH v2] clk: at91: Fix a return value in case of error

[Christophe JAILLET]

If 'clk_hw_register()' fails, it is likely that we expect to return an
error instead of a valid pointer (which would mean success).

Fix commit f5644f10dcfb ("clk: at91: Migrate to clk_hw based registration
and OF APIs")

v2: clk_hw_register does return an error or 0. So we can use it. 

This proposal is un-compiled and un-tested.
I get an error when I run 'make drivers/clk/at91/' which is likely due to
my building environment.
