Segmentation fault with dpctl.tensor.argsort on CPU device

[antonwolfy]

The below example crashes with Segmentation fault while running on CPU device:

import dpctl.tensor as dpt
from numpy.random import default_rng

N = 4 * 10**6
rng = default_rng(42)
a = rng.random((N,))

ia = dpt.asarray(a, device='cpu')
block_size = 65536

for i in range(0, len(ia), block_size):
    tmp_ia = ia[i : i + block_size]
    sorting_index = dpt.argsort(tmp_ia)

The callstack from `gdb` output

I can reproduce. The crash is sporadic, sometimes the script runs fine, but chances of it happenning are higher if more RAM is available.

The reason for crash is memory access violation. Could not reproduce the crash with sort.
