[PATCH 6.18.y 2/2] PCI/pwrctrl: generic: Fix leaking array from of_regulator_bulk_get_all()

[Sasha Levin <sashal@kernel.org>]

From: Alexey Charkov <alchark@flipper.net>

[ Upstream commit ee450e3a2d334c7e6383d8a55ad2d53b3822bacc ]

of_regulator_bulk_get_all() allocates the consumers array and returns it to
the caller, who is expected to free it at an appropriate time.  PCI pwrctrl
never did, leading to a memory leak.

Add an explicit kfree() for the consumers array.

Fixes: 75996c92f4de ("PCI/pwrctrl: Add pwrctrl driver for PCI slots")
