[PATCH v2] iio: adc: pac1921: Move ACPI_FREE to cover all branches

[victor.duicu]

From: Victor Duicu <victor.duicu@microchip.com>

This patch moves ACPI_FREE in pac1921_match_acpi_device
in order to cover all branches.

Reported-by: Andy Shevchenko <andy.shevchenko@gmail.com>
Fixes: 9fdf1d033316 ("iio: adc: pac1921: Add ACPI support to Microchip pac1921")
Signed-off-by: Victor Duicu <victor.duicu@microchip.com>
---

This patch ensures that status is freed before
exiting the function.

Differences related to previous versions:
v2:
- add Fixes tag.
- remove unnecessary blank line.

v1:
- initial version for review.

Just a reminder that in v1, I think Andy suggested to edit the commit
message by adding parenthesis to the function name. I also find it more
clear.
