[PATCH] iio: pressure: abp2030pa: Remove unreachable return in abp2_read_raw()

[Babanpreet Singh]

In the IIO_CHAN_INFO_RAW case every arm of the inner switch on
channel->type returns - IIO_PRESSURE and IIO_TEMP return IIO_VAL_INT and
default returns -EINVAL - so the "return IIO_VAL_INT;" following that
switch cannot be reached. The sibling IIO_CHAN_INFO_SCALE and
IIO_CHAN_INFO_OFFSET cases have the same shape and no trailing return,
so drop it here as well.

Found by smatch:
drivers/iio/pressure/abp2030pa.c:382 abp2_read_raw() warn: ignoring unreachable code.

No functional change: the compiler already discarded the statement, and
the generated object code is identical before and after.
