[PATCH 9/9] lib: fwts_acpi_tables: check table to avoid dereferencing NULL ptr

[Colin King]

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

Static analysis from clang scan-build detected a potential NULL
pointer deference on table; fwts_acpi_get_table() can potentially
return NULL, so check for this corner case.
