efi_loader: add missing EFI_CALL around tcg2 read_blocks calls

The read_blocks() function from the Block IO protocol is a UEFI function;
make sure to call it from within U-Boot using the EFI_CALL() macro.

To demonstrate the issue on an AArch64 machine, define the DEBUG macro in
include/efi_loader.h and build u-boot with sandbox_defconfig, then download
and uncompress the ACS-DT image [1], and finally execute the following
command:

  $ ./u-boot -T -c " \
      host bind 0 systemready-dt_acs_live_image.wic; \
      setenv loadaddr 0x10000; \
      load host 0 \${loadaddr} EFI/BOOT/Shell.efi; \
      bootefi \${loadaddr} \${fdtcontroladdr}"

The following assertion should fail:

  lib/efi_loader/efi_net.c:858: efi_network_timer_notify: Assertion `__efi_entry_check()' failed.

This happens due to the following EFIAPI functions call chain:

  efi_start_image()
    efi_disk_read_blocks()
      (due to the missing EFI_CALL, entry_count == 2)
      efi_network_timer_notify()
