mesa: Fix indirect draw buffer size check on 32-bit systems.
Fixes dEQP-GLES31.functional subtests:
draw_indirect.negative.command_offset_not_in_buffer_signed32_wrap
draw_indirect.negative.command_offset_not_in_buffer_unsigned32_wrap
These tests use really large values that overflow GLsizeiptr, at
which point the buffer size isn't less than "end".
