iio:pressure: zpa2326: remove redundant "DEBUG" ifdef
The -Wempty-body gcc warning triggers in the newly added zpa2326 driver:
drivers/iio/pressure/zpa2326.c: In function 'zpa2326_dequeue_pressure':
drivers/iio/pressure/zpa2326.c:578:3: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
The use of an empty statement behind 'if (...)' is harmless here, but
it shows that the dev_dbg() macro is not used correctly: when the "DEBUG"
macro is not set, dev_dbg() already defaults to a no-operation, though
one that lets the compiler know that the arguments are used, and lets
it check the format string.
Fixing this also simplifies the driver.
