ublk: Fix signedness bug returning warning
There are two warnings reported by smatch:
drivers/block/ublk_drv.c:445 ublk_setup_iod_zoned() warn:
signedness bug returning '(-95)'
drivers/block/ublk_drv.c:963 ublk_setup_iod() warn:
signedness bug returning '(-5)'
The type of "blk_status_t" is either be a u32 or u8, but this two
functions return a negative value when not supported or failed. Use
the error code of the blk module to fix these warnings.
Fixes: 29802d7ca33b ("ublk: enable zoned storage support")
