This commit uses `string.SplitN` instead of `string.Split`.
The path for pids.max has extra `:` symbols in it due to which
getCgroupPidsFile() splits the string into 5 tokens instead of
3 leading to loss of part of the path.
As a result, the below error is reported:
`Failed to get the PID limit, can not reconfigure: open
/sys/fs/cgroup/pids/system.slice/containerd.service/
kubepods-besteffort-pod183b9d14_aed1_4b66_a696_da0c738bc012.slice/pids.max:
no such file or directory`
SplitN takes an argument n and splits the string
accordingly which helps us to get the desired
file path.
Fixes: #2337

nlreturn linter requires a new line before return
and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

The internal/ directory in Go has a special meaning, and indicates that
those packages are not meant for external consumption. Ceph-CSI does
provide public APIs for other projects to consume. There is no plan to
keep the API of the internally used packages stable.
