exfat_err() adds the new line at the end of the message by itself,
hence the passed string shouldn't contain a new line. Drop the
superfluous newline letters in the error messages in a few places that
have been put mistakenly.

The ENAMETOOLONG error message is printed at each time when user tries
to operate with a too long name, and this can flood the kernel logs
easily, as every user can trigger this. Let's downgrade this error
message level to a debug message for suppressing the superfluous
logs.

This code calls brelse(bh) and then dereferences "bh" on the next line
resulting in a possible use after free. The brelse() should just be
moved down a line.

kbuild test robot reported :
fs/exfat/nls.c:531:22: warning: Variable 'p_uniname->name_len'
is reassigned a value before the old one has been used.
The reassignment for p_uniname->name_len is not needed and remove it.

To clarify that it is a 16-bit checksum, the parts related to the 16-bit
checksum are renamed and change type to u16.
Furthermore, replace checksum calculation in exfat_load_upcase_table()
with exfat_calc_checksum32().

Remove the direct use of KERN_<LEVEL> in functions by creating
separate exfat_<level> macros.
Miscellanea:
o Remove several unnecessary terminating newlines in formats
o Realign arguments and fit to 80 columns where appropriate
