When the driver tries to map a region, but the region has certain
permissions, or when it attempts to open gasket with tgid, or when it
realeases device node; the logs are displayed in one line only while the
code has the strings split in two lines which makes it difficult for
developers to search for code based on the log messages. So, this patch
fixes three warnings of 'quoted string split across lines' in
gasket_core.c by merging the strings in one line.

Also, I wasn't sure if I were to send a separate batch or reply with a
v2 for this one. If former was the case than please let me know.
Thanks for your time!
