mailbox: PCC: handle parse error
acpi_pcc_probe() calls acpi_table_parse_entries_array() but fails
to check for an error return. This in turn can result in calling
kcalloc() with a negative count as well as emitting the following
misleading erorr message:
[ 2.642015] Could not allocate space for PCC mbox channels
Fixes: 8f8027c5f935 (mailbox: PCC: erroneous error message when parsing ACPI PCCT)
