[PATCH 4/4] accel/habanalabs: add missing error flow in hl_sysfs_init()

[Oded Gabbay]

From: Tomer Tayar <ttayar at habana.ai>

hl_sysfs_fini() is called only if hl_sysfs_init() completes
successfully. Therefore if hl_sysfs_init() fails, need to remove any
sysfs group that was added until that point.
