[PATCH 5.10 074/152] habanalabs: Fix memleak in hl_device_reset

[Greg Kroah-Hartman]

From: Dinghao Liu <dinghao.liu@xxxxxxxxxx>

[ Upstream commit b000700d6db50c933ce8b661154e26cf4ad06dba ]

When kzalloc() fails, we should execute hl_mmu_fini()
to release the MMU module. It's the same when
hl_ctx_init() fails.
