Details:

The goto freepbuf code path is also used when IP_REASS_CHECK_OVERLAP=0.
Thus remove #if IP_REASS_CHECK_OVERLAP around the freepbuf label to fix
below build error:

cc -g -Wall -DLWIP_DEBUG -pedantic -Werror -Wparentheses -Wsequence-point
-Wswitch-default -Wextra -Wundef -Wshadow -Wpointer-arith -Wcast-qual
-Wc++-compat -Wwrite-strings -Wold-style-definition -Wcast-align
-Wmissing-prototypes -Wredundant-decls -Wnested-externs -Wunreachable-code
-Wuninitialized -Wlogical-op -I. -I../../.. -I../../../../lwip/src/include
-I../../../ports/unix/port/include -I../../../../mbedtls/include
-Wno-redundant-decls -DLWIP_HAVE_MBEDTLS=1 -c

       goto freepbuf;
