scsi: ufs: Fix off-by-one bug in ufs debugfs driver
When getting string from userspace by simple_write_to_buffer
in ufs_qcom_dbg_testbus_cfg_write() function, null byte may
be written out of bounds of configuration buffer if return
value is same as size of buffer, causing off-by-one bug.
This change passes correct available size of configuration
buffer to simple_write_to_buffer function.
