devmem2: fix output when _FILE_OFFSET_BITS=64
When built with _FILE_OFFSET_BITS=64, off_t becomes an long long int and was printed as an unsigned int which lead to a garbled output.

+Subject: [PATCH] be coherent in type usage
+
+- no need to use off_t because it is read from strtoul()
+- print unsigned int type correctly
+
+When built with _FILE_OFFSET_BITS=64, off_t becomes an long long int
+and was printed as an unsigned int which lead to a garbled output.
