platform/x86: hp-bioscfg: prevent a small buffer overflow

This function escapes certain special characters like \n.  So if the
last character in the string is a '\n' then it gets changed into two
characters '\' and '\n'.  But maybe we only have space for the '\' so
we need to check for that.

The "conv_dst_size" variable is always less than or to equal the "size"
variable.  It's easier to just check "conv_dst_size" instead of checking
both.
