tpm: loongson: Add bufsiz parameter to tpm_loongson_send()

Commit 5c83b07df9c5 ("tpm: Add a driver for Loongson TPM device") has a
semantic conflict with commit 07d8004d6fb9 ("tpm: add bufsiz parameter
in the .send callback"), as the former change was developed against a
tree without the latter change. This results in a build error:

  drivers/char/tpm/tpm_loongson.c:48:17: error: initialization of 'int (*)(struct tpm_chip *, u8 *, size_t,  size_t)' {aka 'int (*)(struct tpm_chip *, unsigned char *, long unsigned int,  long unsigned int)'} from incompatible pointer type 'int (*)(struct tpm_chip *, u8 *, size_t)' {aka 'int (*)(struct tpm_chip *, unsigned char *, long unsigned int)'} [-Wincompatible-pointer-types]

        |            ^~~~~~~~~~~~~~~~~

Add the expected bufsiz parameter to tpm_loongson_send() to resolve the
error.
