Mark Rutland 9dcbf46655 ARM: perf: simplify __hw_perf_event_init err handling ...

Currently __hw_perf_event_init has an err variable that's ignored right
until the end, where it's initialised, conditionally set, and then used
as a boolean flag deciding whether to return another error code.

This patch removes the err variable and simplifies the associated error
handling logic.
