Eugeniu Rosca e63bf1b13b common: image-android-dt: Fix out-of-bounds access
Currently, 'dtimg' allows users to check indexes equal to
dt_entry_count [1]. Forbid that [2].

[1] Behavior w/o the patch:

=> ext2load mmc 0:1 0x48000000 dtb.img
105695 bytes read in 5 ms (20.2 MiB/s)

=> dtimg dump 0x48000000
dt_table_header:
               magic = d7b7ab1e
          total_size = 105695
         header_size = 32
       dt_entry_size = 32
      dt_entry_count = 2
   dt_entries_offset = 32
           page_size = 4096
             version = 0
dt_table_entry[0]:
             dt_size = 105599
           dt_offset = 96
                  id = 0b779520
                 rev = 00000000
           custom[0] = 00000000
           custom[1] = 00000000
           custom[2] = 00000000
           custom[3] = 00000000
           (FDT)size = 105599
     (FDT)compatible = shimafuji,kingfisher
dt_table_entry[1]:
             dt_size = 105599
           dt_offset = 96
                  id = 0b779530
                 rev = 00000000
           custom[0] = 00000000
           custom[1] = 00000000
           custom[2] = 00000000
           custom[3] = 00000000
           (FDT)size = 105599
     (FDT)compatible = shimafuji,kingfisher

=> dtimg size 0x48000000 0 z; print z
z=19c7f
=> dtimg size 0x48000000 1 z; print z
z=19c7f
=> dtimg size 0x48000000 2 z; print z
z=d00dfeed
=> dtimg size 0x48000000 3 z
Error: index > dt_entry_count (3 > 2)

[2] Behavior with the patch:

=> dtimg size 0x48000000 0 z; print z
z=19c7f
=> dtimg size 0x48000000 1 z; print z
z=19c7f
=> dtimg size 0x48000000 2 z
Error: index >= dt_entry_count (2 >= 2)
