proc: enclose desc variable of show_stat() in CONFIG_SPARSE_IRQ
Impact: restructure code to fix compiler warning
commit 240d367b4e6c6e3c5075e034db14dba60a6f5fa7 moved desc usage point
into #ifdef CONFIG_SPARSE_IRQ.
Eliminate the desc variable, otherwise following warning happens:
fs/proc/stat.c: In function 'show_stat':
fs/proc/stat.c:31: warning: unused variable 'desc'
[ akpm: cleaned up the patch to remove #ifdef ]
