tpm: acpi: Call acpi_put_table() to fix memory leak
The start and length of the event log area are obtained from
TPM2 or TCPA table, so we call acpi_get_table() to get the
ACPI information, but the acpi_get_table() should be coupled with
acpi_put_table() to release the ACPI memory, add the acpi_put_table()
properly to fix the memory leak.
While we are at it, remove the redundant empty line at the
end of the tpm_read_log_acpi().
