kdumpctl: drop _get_current_running_kernel_path

Browse Source 
_get_current_running_kernel_path is identical to
_find_kernel_path_by_release $(uname -r) so simply use this instead of
defining a new function.

While at it simplify reset_crashkernel slightly. This changes the
behavior of the function for the case when KDUMP_KERNELVER is defined
but no kernel with this version is installed. Before, the missing
kernel is silently ignored and the currently running kernel is used
instead. Now, kdumpctl will exit with an error.
