[PATCH] trace-cmd: Fix writing of uncompressed size

[Steven Rostedt <rostedt@goodmis.org>]

From: Sven Schnelle <svens@linux.ibm.com>

pointer in struct tracecmd_compression is 'unsigned long', which is 8 byte
in size on most platforms, but the tep_read_number() call in the next line
treats it as a 4 byte value. As there's no need for unsigned long change
the type to unsigned int.
