net: ethernet: ti: netcp: fix pm_runtime usage counter leak on error

Browse source

pm_runtime_get_sync() leaves the runtime PM usage counter incremented even
when it fails, but the error path in netcp_probe() does not call
pm_runtime_put_noidle() to balance it, leaking a reference each time
resume fails.

Use pm_runtime_resume_and_get() instead, which automatically drops the
usage counter on failure, fixing the leak.
