[PATCH fs/proc/bootconfig] remove redundant comments from /proc/bootconfig

[Paul E. McKenney]

commit 717c7c894d4b ("fs/proc: Add boot loader arguments as comment to
/proc/bootconfig") adds bootloader argument comments into /proc/bootconfig.

/proc/bootconfig shows boot_command_line[] multiple times following
every xbc key value pair, that's duplicated and not necessary.
Remove redundant ones.

Output before and after the fix is like:
key1 = value1
*bootloader argument comments*
key2 = value2
*bootloader argument comments*
key3 = value3
*bootloader argument comments*
...

key1 = value1
key2 = value2
key3 = value3
*bootloader argument comments*
...

/proc/bootconfig")
