tpm: acpi: Call acpi_put_table() to fix memory leak
commit 8740a12ca2e2959531ad253bac99ada338b33d80 upstream.
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().
Fixes: 0bfb23746052 ("tpm: Move eventlog files to a subdirectory")
Fixes: 85467f63a05c ("tpm: Add support for event log pointer found in TPM2 ACPI table")
