Fix an error during ethernet probe (deferred because IOExpander used for
Reset Ethernet of STM32MP13-DK is not ready).
The pb is the Ethernet probe initialize pm-runtime but when error occur 
and exit from probe there is no deinit of pm-runtime so when the reprobe
is called (after init of IOExpander) pm-runtime is already enable and
the balance between "put" and "get" is not symmetric, so Ethernet genpd
is always active. 

Already review on series pushed on :
18/02/2026 https://lkml.iu.edu/2602.2/02822.html, 
and 04/08/2026 https://lkml.iu.edu/2608.0/08550.html
