Fix sparse warnings:
drivers/staging/exfat/exfat_core.c:2045:4: warning: symbol
'calc_checksum_1byte' was not declared. Should it be static?
drivers/staging/exfat/exfat_core.c:2080:5: warning: symbol
'calc_checksum_4byte' was not declared. Should it be static?
The two functions has no caller in tree, so remove it.
