regulator: core: use kfree_const() to free space conditionally

Browse Source 
[ Upstream commit dc8d006d15 ]

Use kfree_const() to free supply_name conditionally in create_regulator()
as supply_name may be allocated from kmalloc() or directly from .rodata
section.

Fixes: 87fe29b61f ("regulator: push allocations in create_regulator() outside of lock")
