select: Fix unbalanced user_access_end()
While working on implementing user access validation on powerpc
I got the following warnings on a pmac32_defconfig build:
CC fs/select.o
fs/select.o: warning: objtool: sys_pselect6+0x1bc: redundant UACCESS disable
fs/select.o: warning: objtool: sys_pselect6_time32+0x1bc: redundant UACCESS disable
On powerpc/32s, user_read_access_begin/end() are no-ops, but the
failure path has a user_access_end() instead of user_read_access_end()
which means an access end without any prior access begin.
Replace that user_access_end() by user_read_access_end().
Fixes: 7e71609f64ec ("pselect6() and friends: take handling the combined 6th/7th args into helper")
