net: pse-pd: Fix deadlock in current limit functions
commit 488fb6effe03e20f38d34da7425de77bbd3e2665 upstream.
Fix a deadlock in pse_pi_get_current_limit and pse_pi_set_current_limit
caused by consecutive mutex_lock calls. One in the function itself and
another in pse_pi_get_voltage.
Resolve the issue by using the unlocked version of pse_pi_get_voltage
instead.
Fixes: e0a5e2bba38a ("net: pse-pd: Use power limit at driver side instead of current limit")
