[PATCH 5.10 150/599] spi: spi-zynqmp-gqspi: Handle error for dma_set_mask

[Greg Kroah-Hartman]

From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit 13262fc26c1837c51a5131dbbdd67a2387f8bfc7 ]

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

Fixes: 126bdb606fd2 ("spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails")
