[PATCH] power: fix pstate number parsing

[Markus Theil <markus.theil@tu-ilmenau.de>]

From: Markus Theil <markus.theil@secunet.com>

When converting atoi to strtol in a revision
of introducing sysfs support for turbo percentage,
a necessary check against '\n' returned by sysfs
was not introduced.

Fixes: de254dac608e ("power: read P-state turbo percentage from sysfs")
