Since -Werror is enabled by default build fails with:
```
In function '__bswap_32',
    inlined from 'do_rpmb_write_block' at mmc_cmds.c:2293:27:
/home/autobuild/autobuild/instance-15/output-1/host/aarch64-buildroot-linux-gnu/sysroot/usr/include/bits/byteswap.h:52:10: error: 'cnt' may be used uninitialized [-Werror=maybe-uninitialized]
   52 |   return __builtin_bswap32 (__bsx);
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~
mmc_cmds.c: In function 'do_rpmb_write_block':
mmc_cmds.c:2270:22: note: 'cnt' was declared here
 2270 |         unsigned int cnt;
      |                      ^~~
cc1: all warnings being treated as errors
```
So let's fix the warning by initializing cnt local variable.
