IIO fixes for v3.6-rc1 set 2

A few simple fixes.

1)Fix up some possible divide by zero issues in various drivers.

2)Prevent a memory leak in an error path in lis3l02dq

3)Make sure the PTR_ERR call in at91_adc matches the
check for IS_ERR just above it rather than using a different
pointer.

Merges fine against v3.6rc4
