[PATCH] lib: fwts_acpi_tables: unmap mem, fixes memory leak

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

I forgot to unmap mem before returning from the function, causing a
memory leak. Fix this by unmapping it.

Fixes: f327fcea6f81 ("lib: fwts_acpi_tables: re-work fwts_acpi_get_rsdp, less memory copies")
