[src/atan.c] Fixed bug in mpfr_atan: mpfr_check_range was called on the
unrounded result (no longer allocated) instead of the rounded result.
Consequence of this bug: possible incorrect or invalid result and/or
incorrect flags if either the unrounded result or rounded result is not
in the current exponent range. Or possibly worse if the memory used by
the unrounded result is modified before the return of the function.
