Subject: [PATCH 5/6] samples: fix warnings in uhid-example

Fix following warnings seen when building using i686:
uhid-example.c: In function ‘uhid_write’:
uhid-example.c:168:4: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘ssize_t’ [-Wformat=]
uhid-example.c:168:4: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘unsigned int’ [-Wformat=]
uhid-example.c: In function ‘event’:
uhid-example.c:239:4: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘ssize_t’ [-Wformat=]
uhid-example.c:239:4: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘unsigned int’ [-Wformat=]

Use "%xd" for arguments of type size_t to fix the warnings.
