media: atomisp: use IA_CSS_ERROR() for error messages in sh_css_mipi.c

Some debug messages for error cases (messages contain "error: ") use
IA_CSS_DEBUG_TRACE_PRIVATE debug level. This causes these error messages
not to appear unless users raise debug output level to 7 or higher (using
module parameter, dbg_level=7).

So, use IA_CSS_DEBUG_ERROR debug level (dbg_level=1) instead considering
that these are error messages. There is already a macro IA_CSS_ERROR()
for this use case. Let's use it. It automatically appends "error: " at
the beginning and a newline to a message. Therefore, we can remove them
from these messages.

While here, remove the unnecessary newline from one IA_CSS_ERROR()
occurrence in the same file.
