spi: spi-zynqmp-gqspi: Handle error for dma_set_mask

stable inclusion
from stable-v5.10.110
commit b7940bef6f21f23955661d476c9760e6b046d21b
bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b7940bef6f21f23955661d476c9760e6b046d21b

--------------------------------

[ Upstream commit 13262fc2 ]

As the potential failure of the dma_set_mask(),
it should be better to check it and return error
if fails.

Fixes: 126bdb60 ("spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails")
